investigated the
grafting of other polymers on the saue material. For this,
FTFE was dipped
into the monomer, the polymer and the monomer then being
exposed
simultaneously to high-energy radiation. Sinitsina et al.
(Ref. 4) applied
a different method. In the present paper, the first-mentioned
method was
used. The authors used a 220 kv, 15 ma X-ray apparatus, or in
some cases,
a 60 curie Co 60 source. Styrene, methyl metha.cryaate, vinyl
acetate, and
vinyl pyridine were used as monomers. Irradiation was carried
out in the
absence of oxygen. Vinyl acetate was grafted most easily.

most suitable for
coloring graft polymers (Table 1, Fig. 3), the choice of
dye, however,
depending on the type of grafted polymer (Table 2, coloring
conditions for
vinyl acetate copolymers). Investigation data show that well
colorable
PTFE sheeting can be prepared by radiation-initiated
grafting, without
appreciable damage to the mechanical properties of the
sheeting, provided
the.grafted polymer coating is thin (Tables 3, 4). The color
gives an idea
of the distribution of colorable grafted components in the
sheeting. At
room temperature and medium intensities, grafting on PTFE is
a surface

TITLE; Production of dye-absorbent Teflon by radiation-chemical
graft copolymerization
PERIODICAL: Magyar K4miai Poly6irat, no. 2, 1961, 85-90
TEXT: The grafting of styrene on Teflon was studied by A.
Chapiro (Ref. 1:
J. Polymer Sci., 34, 481, 1959), and that of other monomers on
Teflon by
A. J. Restaino (Ref. 2: Harwood: Effects of Radiation on
Materials,
Reinhold, New York, 1958, Chapt. XI; Ref. 3: As J. Restaino and
W. N.
Reed: J. Pol. Sci., 36, 499, 1959); in the latter case, graft
copolymeriza-
tion and homopolymerization occurred at the same time. Ts. A.
Sinitsyna,
I. D. Tsvetkov, G. S. Bagdasaryan, and V. Voyevodskiy (Ref- 4:
Dokl. Aka
Nauk, 129, 631, 1959) were the first to irradiate Teflon and
immerse it
into the monomer; thus, long-lived free radicals were formed on
Teflon,
and graft copolymerization of the monomer was initiated. A
communication
by the Radiation Application Co. (Ref, 5: Chem. Eng. News:
37/59 449
1959) mentions a procedure of radiation-chemical graft
copolymerization

for the production of dye-absorbent Teflon without describing
it in detail.
Polymer and monomer were simultaneouelf irradiated by a 220-kv
and 15-ma
X-ray apparatusp in some cases by a Cc 0 radiation gun with an
activity
of 60 curie~.with exIlusion of oxygen. Results obtained are
described
in Ref. 6 (J Dob6, . Somogyi: Journ. chim. Phys., 56, 863,
1959)-
Monomers used were styrene, methyl methacrylate (MMA), vinyl
acetate (VAC),
and vinyl pyridine (VP). To attain a given degree of grafting,
the
radiation dose required rises in the order: VAC, MMA, VP,
styrene (Fig. 1).
VP copolymers can be best stained with acid and acetate dyes,.
MMA
copolymers worse, and sulfonated styrene copolymers worst.
Thus, the use
of VAC is most convenient. Grafting on Teflon is connected with
auto-
acceleration increasing with time (Fig. 2). The initial
grafting rate
is approximately proportional to the square ro6t of the
radiation intensity;
grafting is accelerated by a temperature increase. Table 1
gives a
survey of the dyeing of grafted copolymers; the data were
obtained in a
dyestuff bath within 1 hr and at 1000C, a 2% aqueous dyestuff
solution,
a 1% emulsifier solution, and benzene being used as carriers.
Under these
conditions, ungrafted foils were not stained at all. Slightly
(below 2%)
grafted foils were stained irregularly due to irregular
grafting. Uniform,
^ - -.3 n /4n

Production of dye-absorbent Teflon by ... B124/B203
well-dyed foils were obtained by a 6-101/6 grafting with VAC, for
example
(Table 2). The penetration depth of dyes into the polymer foil is
independent of diffusion, and represents the distribution of
grafted
polymer in the foil. The mechanical properties of Teflon
deteriorate only
slightly under the action of radiation (Table 3). The thermal
stability
of the dye depends on the grafted polymer and the dyestuff
quality; with
certain combinationsg thermal stability is very high (Table 4).
Grafting
of Teflon proceeds at room temperature and medium intensities in
the
surface layer. J&nos Ydkes is thanked for assisting in
photographing
the microzcopic sections. There are 3 figures, 4 tables, and 6

TITLE: Contribution to the radiation-ohemical polymerization of
cetylic methacrylate
PERIODICAL: Plaste und Kautschuk, vol. 9, no. 4, 1962, 188 - 189
TEXT: In addition to tests carried out by Doctor G.Hardy in the
Hungarian
Research Institute for the Plastics Industry concerning the
polymerization
of cetyld:c methacrylate (ZIAA), the authors examined the
radiation-chemical
polymerization of commercial purified ZMA. The irradiation was
effected by,
an X-ray apparatus of 220 kV and 15 mA at 400C. The irradiation
intensity
amounted to 40,000 r/h. Due to traces of inhibitors, the
polymerization
commences after a period of induction and reaches a constant
velocity of
to 406 of the transformation. The polymerization velocity amounts
to la;4?h
or 1.4*10-4 Mol/1-s. The linear dependence of the transformation
on time
presupposes a certain auto-aoceleration (Gel effect).* Author K.

ABSTRACT: The thermal decomposition of ammonium perchloraie was
studied in the
presence Of low concentrations (below 1%) of different impurities,
such as iodide,
-bromide, silver(I), copper(II) and iron(III) ions. Detailed kinetic
measurements
vere made between 200 and 240C as well as 260 and 330C. In the lower
temperature
range all the impurities decrease the induction period and increase
the rate of
decomposition of ammonium perchlorate. The.activation energies found
for the cata-
lytic decomposition are in good agreement'vith the values
corresponding to a, process
occuring via an electron transfer mechanism. At above 260C the

"Method for the Counting of Megakaryocytes in the Bone
Marrow of Mice."
Budapest, Kiserletes Orvostudomany, Vol XVIII, No 5, Oct
66, pages 542-546.
Abstract: [Authors' Hungarian summary] The experimental
studies of thrombo-
cytopoiesis were lacking in a method suitable for the
quantitative determina-
tion of bone-marrow me(rakaryocytes in mice. The few
methods described in the
literature were found unsuitable in mice experiments. A
method is described
which, according to the experiences gained so far,
provides satisfactory
information concerning the megakaryocyte content of the
mouse femur and the
results obtained are reproducible. The results are
reported in terms of a
so-called megakaryocyte index. The method appears to be
suited to provide
information about changes in the megakaryocyte stock of
the bone marrow in
case of changes in the thrombocyte count effected or
developed by various
means. I Hungarian, 3 Western references. [Manuscript

By machining at a cutting speed of 10 m/see and 1,250 rpm,
with Soviet
rubber-bonded silicon carbide cup grinding wheelg 150 mm in
diameter,
a surface finish of 0.32,4 was obtained. The abrasion of both
the tip
and grinding wheel was even but rather highg probably due to
the soft
bonding material and high revolution. When using a paste of
80% kero-
sene and 20% of 120 and 400 grit boron carbide in a "UE 17511
laboratory
grinding machine with a special grinding apparatus, the
surface finish
at a cutting speed of 2.4 mm/sec. was 0.25 /1 and 0.2 A ,
respectively.
Machining with a commercial diamond wheel gave a surface
finish of 0.3.4
Microscopic photos of the faces also proved that best results
were
achieved with 400 grit boron carbide paste and that the
surface finish
obtained with the Soviet silicon carbide wheel approximates
the quality
achieved by diamond wheel. Tests revealed that the smaller the
roughs,
ness, the higher the life of the tip; this is especially true
during the
early wearp The life of the tips with various surface finishes
as
plotted against their abrasion, measured at the end of the
cutting edge
in machining C 35 steel with 15hn 160 kg/sq mm, is shown in
Fig, 10.

Bulletins of the D277/1)301
Although a surface finish approximating to that made with a
diamond
wheel can be achieved with boron carbide or special silicon
carbide
abrasives, for shop practice it must be taken into consideration,
that grinding with boron carbide takes 2-3 minutes, while a
silicon
carbide wheel can he used due to the high wear for grinding
240-250
tips at the most. There are 10 figures.

ABSTRACT: The magnitude of deformation (D) in the various
parts of a
sectional groove roller(R) has been investigated, and it
is est-
ablished that the volume of metal squeezed by the collar
of the
R in the active area of D goes in its entirety to
compensate for
the reduction in the cross-section of the flanges due to
bending,
while the volumes of metal above the upper and below the
lower
tapers go to spread and elongate the strip. Analysis of
the na-
ture of D provides a formula for determining the length of
the
billet to be used in sectional RI a: Ho=bp
hp/3(Bd-.bp4H. where
Ho is the height of the billet delivered to the sectional
,b p is
the base of the sectional collar, h P is the height of the
collar,
Hp As the height of the sectional R, B6=(BO+Bp)/2 is the
average
width)and B9 is the width of the sectional R.
