TITLE: Fraotional~compositiqh of polyamides synthesized at an
interface under. static conditions
PERIODICAL: Khimiabeekiye voloknal no. 11 196~0 17-19
TEXT: A film formed at the interface of sebaoyl diohloride dissolved in
chloro benzene and hexamethylene diamins dissolved in water oontaining
NaRCO This was drawn out without mixing the solutions, and its
3~
fractional composition was tooted. Polymers with a degree of polymeriza-
tion (DP) between 87 and 143 were obtained by changing the concentration
of the sebacyl dichloride from 8,to 10% by weight,,and that of the hexa-
methylene diamine from 1 to 5% by weight. Comparison-with the fractional
composition of polycaprolactam pol.ymerized in the melt showed that the
DP covers a wider range on interfacial polymerization than on melt
polymerization, but the fractions-with a DP of 50T200 predominate in
both polymers, The interfacially polymerized polymer is characterized
by.fractions with DP up to 600, but the content of highly polymerized

Fractional composition of polyamidee ... B101/B186 .
fraction (DP>200) is only 18-19%. The maximum on the differential curve
lies at lower DP for the interfacial polymer than for polydaprolaotam.
Similar results were obtained by comparing the interfacial polymer with
polyhexamethylene adipic amide,produoed..by thermal polymerization of AR
salt.. P.olyhexamethylene adipic-amido'had an average DF of164. 'with a-
maximum at--DP-105, thile t,he.respective values for the interfacial
polymer were 143,and 75- Conclusion: Interfacial polymerization at first
proceeds irreversibly at a rate.oorresponding to the range of ionic
reactions, go that no secondary reactions occur. After formation of a-.
--monomolecular layer, the,rate of polymerization depends on monomer a
diffusion through the layer. Due to the changes.in concentration, the
rate of diffusion finally becomes commensurate with the rate of termin'a-
ti n. The

TEXT: Improved schemes and rapid methods are suggested for determining all
known-polyamide fibers (including Enant and Pelaigon), based on
analyzing their solubility in different solvents, Methods are
recommended for the qualitative and quantitative determination of
Caprone and Anid fibers mixed with cotton, wool and viscose staple fibers.

TITLE:- Photoelectron emission by gold and chromium
PERIODICAL: Fizika tverdogo tela, v. 3t no. 6, ig6i, 1629 - 1637
TEXT: By way of an introduction, a very detailed discussion is offered on
some papers by Thomas, Mayor et al,. (H. Thomas, Zs. f. Phys, 147, 4, 395,
1957; H. Mayer, R. Nossek, H. Thomas. J. Phys. Rad. E, 204, 1956;

1471 49 465v 1957; S. Methfessel, Zs. f. Phys., 147, 4, 1957), which
contain reports on the photoelectron emission of potassium films; the
abovementioned authors have stated that photoelectron emissioz, Jn this metal
is of the volume type. The correctness of such a conclusion ap:.,e,.irs, how-
ever, to be dubious, and the problem of the nature of photoelectron emis-
aion cannot yet be considered as being definitely solved. The authors of
the present paper have therefore again studied the phenomenon of photoelec-
tron emission. They chose gold and chromium for their purpoces, because the
excitation energy of "plasmons" in these metals is considerr--bly higher

The effect of adsorbed BaO was examined first. The volt-ampere character-
istics obtained showed the maximum change of the thermo-electronic work funo-
tion, that depended on BaO adsorption, to be about 3.2 - 3.4 ev for gold and
2.8 ev for chromium. The effect of BaO adsorbed an Au and Cr films was
