polymerization of vinyl cyanide in water solutions. P. 1027.
The probleir of this work is the investigation of polymerization ir. water solutionsp
in solutions of emulsif-.ers (in the region of colloid solubility) and in emulsions in
order to clear up the role of the processes going on in the separate parts of the emulsion
system in the general process of emulsion polFinerization. Vinyl cyanide, a i-,ionomer, was
studied first because it is easily sol-i~)lr 411 .Iatcr. Potassium persulfate served as
initiator of the polZrmerization.

Abstract: solution. The influence of these particles can be detected only by
statistical averaging. The presence of such particles is also in-
dicated by the large values of the dissymmetry factor and the tur-
bidity factor. The authors assume that the macroparticles present in
soJution form the seeds of extended layers. The hypothesis postulat-
int, '.he formation of large --nolecules with extendd chains during the
polymerization of styrene with butadiene is also confirmed by the
low rate of increase in the assymmetry of light dispersion and the
reduction in intrinsic viscosity with increasing molecular weight.
It is shown that the heterogeneity of the fractions and chain length
of the copolymer molecules increase with conversion and reaction
temperature.

ABSTRACT: In January 1957, the Second All-Uni.on Conference on Pho*.o-
synthesis took place, organized by the Institute of Plant Phys~-
ology of the Academy of Sciencoe, USSR, and by the Faculty of Soil-
Biology of the Moskva University. About 700 representativen of
130 scientific-research institutes, vuzes and ministries were
present. The in*,roductory report was made by Academician A.L.
Kursanov who described the development of photosynthesis during
the last ten years and invited the scientists to concentrate their
work on the application of radioactive and stable isotopes.
Nearly100 reports were read: 13 on photochemistry, 9 on the in-
vestigation of chloroplast structure, 19 on the invest~gatiozl
of pigments, 9 on the photosynthesis of water plants, Acteria,
etc.
Reports on the results reached in the field of photosynthesis
were made by: Doctor G. Polster from the German Democratic Re-
public, Professor N. Seledzhanu from the Rumanian People's Re-
pliblic, Professor K. Popov from the Bulgarian People's Republic.
Finally the Conference stated the great role Of Soviet Bcien-

USSR Academy of Sciences and the MGD and concentrated on general
matters of polymeric chemistry and physics. About 1500 scien-
tists were pre3ent from 172 organizations and 37 towns of the
Soviet Union, the representatives of 42 vuzes and 17 foreign
scientistn from China, East Germany, Poland, Rumania, Czecho-
slovakia, Yugoslavia, the German Federal Republic and Israel.
The introductory speech was made by Academician V.A. Kargin,
who described the present state of science relating to polymers,
and invited the scientists to concentrate their work on new
methods of obtaining polymers, and new classes of high-molecular
substances. In the section of polymeric synthesis 43 papers
were read. The author enumerates the following reports:
Academician A.N. Nesmeyanov on the reaction of ethylene polymeri-
zation and carbon tetrachloride.
Member-Correspondent of the USSR Academy of
Sciences, on the kinetics of various types of polymerization.
