A13STRACT: The base n-butylglycidyl eater polymer (BGEF) and the phenylglyoidyl
eater polymer (PGEP) were synthesized from the corresponding monomers by block
'polymerization at 90C in the presence of the initiators resorcinolg trimetbylolpro-
.paneq and NaOH. While 30% resoreinol yielded linear polymers of'an average
~Molecular weight of 570, the same amount of trims-thy-lolpropane produced branched
polymers of molecular weights within the 760-775 range. The BGJEP and FGEP polymers!-
so produced were used to make lacquers by being blended with toluileuetWoooyanate

lormed a series of teets,'using various XCOx0H ratios, temperatures, and reac f
'periods. It was found that at 90C satisfactorily hardened films with high physiao-
"mechanical properties and good appearance were obtained by blending the glycidyl
esters of linear structure with TMD, and by blending the polymers of branched
structure with TD or DMD. It was also found that for blends of the linear PGE
polymer with TtM the optimum ratio of NCO:011 was 1-311. This yielded (at 900) a
icompletely hardened film within 6-7 hours. Por the branched BGE and PGE polymers,
the optimal ratios of NCO:OH in their blends with MW were 1-411 and 1.1:1f and thel
hardening periods were I and 3 hours respectively. A period of 16-20 hours was
required for hardening films of the branched 3GE polymer blended with TDI at a
NCO:OH ratio of 1-4:1. The hardness, adhesion, and resistance to chemical agents
of the lacquer films proved them to be of high quality. 0a, A.,Vasillyeva partici-

ABSTRACT: It was establidied that phenyl glycidyl other reacts with oarbanilide
to form hydro.Vl-containing compounds as a resutlt of the interaction between
epoxy and imino, groups; it was postulated that in addition, a reaction is
possible betureen the epoxy groups and the hydroVl groups formed. It was shown
that condensation of butyl other takes place in the course of the reaction of

ABSTRACT: Copolymerization of glycidyl methacrylate (GMA) with styrene in the
presence of reorystallizea dinitryl a2oisobutyric acid and benzoyl peroxide has been
carried out in various solvents at 60 and 120C in a nitrogen atmosphere. The
composition of the resultant copolymers and the monomer reactivity ratios r, and r2
have been calculated by the method of M. Fineman and S. D. Ross (J. Polymer Soi.,
5~ 259, 1950), producing r - 0.55 and r a 0-45. The monomer reactivity ratios

,bicyclo-(2,2,1)-5-heptyl-2,3-dicarboxylic acid with ethyleneglycol, glycerine, and xy-

products as coatings were compared to those based on phthalic anhydride. The rates of
ithe polycondensation reaction and the energies of activation are graphed and tabulated.'
Ilt was found that this polycondensation is a two-stage reaction. The first of these
,stages is fast, almost independent of temperature, and leads to the formation of the f

glycol was found to be 14.5 kcal/mol. All the polycondensation products have lower
acid numbers than those of the corresponding products based on phthalic anhydride. It
is claimed that these polycondensation products lead to higher quality varnishes and

ABSTRACT: The synthesis of buty1methacrylate copolymers (1) with glycidylmetha-
crylate ([I) and methacrylic acid 011) was carried out in cyclohexanone (IV) and
dioxane (V) at 70. 80, and 90C. Benzoyl peroxide (IV) and dinitrile of azodi-iso-
butyric acid (VII) in amounts of 0. 1. 0. 2, 0. 4 and 0. 8 mol % were used as initiatom-
The monomer concentration in the reaction mixture amounted to 20, 30, and 40%
and the molecular ratios varied over a wide range. The copolymerization rate (CR)
increased with an increase in W concentration, while (111) in concentration of less

than.25 mol % was found to retard CR. However, an acceleration of CR was
observed with an increase in the mole fraction of III, accompanied by an increase
in viscosity of the solution, which gelatinizes on reaching a 70% conversion of the
monomer. Such a phenomenon to explained by the capacity of III to form an H-bond
with compounds containing carbonylic oxygen, which is also true for 11, IV and M.
An increase in reaction temperature and in VI and VII concentrations causes an
increase of the rate of copolymerization and a decrease in the molecular weight of
the copolymers. The CR, the molecular weight, and the yield of copolymers
increase with an increase in concentration of the monomers in the solution. IV and
V do not substantially affect CR. The polydispersion of copolymers Increases with,
an increase of I content and also with increases in the reaction temperature and
concentrations of VI and VII. V1 and V do not affect the polydispersion. The
triple thermosetting copolymers obtained are capable of self setting at higher
temperatures. Some properties of the copolymers were determined. V. Agasan-

ABSTRACT: Experiments performed on the removal of lead from Zn con-
centrate in the course of an industrial process have shown that
removal of a portion of the Pb and Cu from the concentrates may
be accomplished by reflotation. The conditions of reflotation de-
pend upon the nature of the relationship among the Pb, Cu and
Zr. minerals. If these minerals are segregated, for the most
part, separation of the Pb m*nerals may be performed after
treatment of the concentrate by elevated amounts of a mixture of
cyanide and chlorine salts of calcium and sodium. If the Pb
minerals are primarily in concretions with ZnS, separation re-
quires very fine grinding of the concentrate. The*best resu

ABSTRACT: To investigate the structure and physical properties of alloys of the com-
pound HiMn with transition elements, the authors fused pseudobinary alloys NiMa-14e
(Ti, V, Cr, Fe, Co, CU) containing 1- 20 at.% V and Ti, and 1- 10 at.% Cr, Fe, Co,
Cu. The tests considered of a dilatometric analysis in the 100 -- 950* interval,
measurements of the electric resistivity as a function of the alloying-additive con-
tent, an electron-microscopic investigation of the structure, and an x-ray phase anal-
ysis. The dependence of the electric properties and of the structure of the alloy as
a function of the heat treatment was tested in the case of-NiMa + 10 at.% V. The
tests yielded the phase compositions of the different alloys and the types of crystal

structure. The results indicate that the observed.higb resistivity of the alloys in
onnected with the structure of the metastable y' plume and depends on the nature of -
the alloying elements. The necessary condition for obtaining the y' phase is quenching
from the unstable 0 phase which exists in such alloys. The resistivity decreased as
a rule with increasing atomic number of the additive, and Increased very strongly with
increasing atomic percentage of the additive. This report vas presented by Acadeniclaft

ISOURCE: Zhurnal prikladnoy mekhaniki i tekhnicheakoy fiziki, no. 6, 1966, 103-104
TOPIC TAGS: fluid flow, flow stability, boundary layer flow
.ABSTRACT: In 1961 it was found that the flow of liquid between two concentric s her
p
the inner one in motion and the external one fixed, becomes unstable at the sphere
2
radius ratio r2 /r1= 2 with a Reynolds number*of about'100 (R = r1 w/v, where w is
the angular velocity of the rotating sphere and v is kinematic viscosity of the
liquid). The solbtion was sought in powers of the Reynolds number; since the ap-
plicability of this method when R is approximately 100 is not obvious, an experiment
was set up to test the theory. A special device was constructed with an inner sphere
of steel, an external sphere of organic glass, and water or commercially pure

that there was no qualitative difference in fluid flow at all Reynolds numbers studied
from the flow previously found in the second approximation. Considerably less intense
motion in the meridian plane is imposed on the circular horizontalrmotion, i6e., on

TITLE: Experimental Study of.the Stability of a Convective Flow
of a Liquid in a Long Vertical Slit
PERIODICAL: Inzhenerno-fizicheskiy zhurnal, 1961, Vol. 4, No. 2,
pp. 106-108
TEXT: The experiments described here were performed on a slit whose
length 1-to-width d ratio was 1/d = 44. One of the plates forming the.slit
was electrically heatable, while the other could be cooled with water
tubes. The power of electric heating decreased linearly from bottom to
top. The difference of temperature between the plat'.es was measured with
thermocouples. Three to four hours after the system was switched on there
appeared a steady state, at which the wall temperature was measured. Three
series of experiments were performed, at which the temperature of' the
cooled- slit Dlate was kept by a thernostat at 11-5, 16.5, and 20.50C,
respectively. Fig. 2 is a graph showing the heated wall temperature

measured in the steady state as a function of the square of the heating

which is near the-Grashof number 1910 obtained theoretically by G. Z.
Gershuni. A turbulent flow appears above this critical value. There are

TITLEt Convection of a liquid in a cavity under conditions of a
boundary layer
PERIODICAL: Inzhenerno-fizicheakiy zhurnalp v- 49 no. 6, 1961j 107 - 110
TEXT: The steady motion of 5a liquid in a vertical slit-shaped cavity in
the interval from 10 to 10 of the Grashof numbers has been studied
using a device described by G. A. Ostroumov (Svobodnaya Konvektsiya v
usloviyakh vnutrenney zadachi (Free convection under conditions of the
internal problem), GITTL 1954). The results found by G. F. Shaydurov
(ZhTF, XXVIII, no. 4, 1958) concerning convection in a spherical cavity
are said to be very interesting. In the middle of a 120*120-40 mm,
parallelelepiped made of babbitt metal, along ist small axis of symmetry,
a 38.6-mm large continuous slit was milled out and covered with window
glass. The cavity formed in this way was filled with distilled water.
A heat current perpendicular to the slit was then produced using an
electric heater and a water-jet cooler. The temperatures on the walls

were measured by copper-constantan thermocouples; the temperature field
inside the liquid was examined by optical methods. The optics used here
differs very little from that suggested by G. A. Ostroumov. The veloci'y
distribution was determined from the motion of light-soattering particles
(aluminum powder) suspended in water by photographing the paths of the
particles. The character of motion of the li id in the slit depends
largely upon the value of the Grashof number ZGUr). For a small Gr, the
velocity distribution in in good agreement with the theory applying to
an infinite slit with isothermal walls. With rising value of Gr (Gr"> 400)
a boundary layer appears on the cavity wall, and a little mobile core
in the center. The maximum of the velocity profile then approaches the
cavity walls, and the temperature practically changes only near them.
In this case, the velocity rises in proportion to Gr1/2, When Gr> 5000,
a peculiar motion occurs in the middle, as has already been described
by G. F. Shaydurov (ZhTF, XXVIII, no. 4, 1958). According to Fig. 1,
not only the velocity but also the temperature gradient in the middle
is opposed to the corresponding quantity in the boundary layer. The
undulatory motion of particles is indicative of a repeated change of
the direction of vertical velocity as a function of the horizontal

coordinate. The formation of regions with a notideable motion in a slit-
shaped cavity can be explained by a vertical. temperature gradient. if a
certain parameter m-exceeds a definite value, the profile of velocity-and
temperature will begin to oscillate, Theory and experiment are in'good
agreement; therefore, the:appe'arance of a"n6ticeable notion of-the liquid
in the middle is probably due to the vertical temperature gradi*ent. Th'V
