should be directed at oxygen-containing active centers of the polymer being ox.16.-
ed. In studying the effect of the mutual action of dithlocarbamate and phenyl-.P
-naphthylamine on the rubber aging process it was seen that. the addition of phenyl-
-p-naphthylamine to a nonfilled thiuram vulcanizate (containing dilhiocarbamate)
is rather effective. However, the effect of phenyl-p-naphthylamine in filled
thiuram rubbers depends on the rubber contained in it. Phenyl-~-naphthylamine
and dithiocarbamate taken together are most effective as inhibitors. Me most
effective salts of dithiocarbamic acid as oxidation inhibitors proved to be the
ethyl and butyl derivatives of zinc, copper and bismuth dithiocarbamates. These
compounds should be used in combination with antioxidants of the amino-class in
order to increase the aging resistance of a number of other types of rubbers

TEXT: This paper on the present state and future trends of Soviet rasearch
in the field of polymer stabilization is dedicated in its first part to
the problem of aging and stabilization of plastic masses, in its second
part to the same prollems for rubbers. Degradation of polymers under the
ac t i on of heat , oxygen, I i ght , and rad i oric t iv e rad iati on is d i sou ssed . Und(r
external affections linkage, formation of struc,ture between the polymer
moleoules may occur. Degradation as well as atructuration lead to unwanted
changes of mechanical and electrical properties of polymeric materials.
Oxidation inhibitors, photostabilizers, aging inhibitors and other ingre-
dients must be added to polymers in order to guarantee their working and to
satisfy technical requirements, Therefore, prodLlCtiOn Of polymers and of
various stabilizers must be developed in par~ille2. Since years K. I. Ivanov

TITLE~- Volatilization of Ingredients from Polymers
PERIODICAL: Kolloidnyy zhurnal, 1960, Vol'kXII, Nr 1, Dp 2-8 (USSR)
AB&TRACT: The present study was carried out to establish the
empiric rules characterizing the behaviour of ingredients
in caoutchouc and rubber under various conditions, and
also to consider the problem from the theoretical stand-
point. Object of the study was the volatilization of an
antioxidant,l phenyl-fl-naphthylamine, from a rubber Dlate,
while heating the latter in a gas current. The investi-
ration method was as follows: Sodium butadiene rubberl?"

tube 18 mm, in diameter, the caoutchouc sample being
placed on a glass support, The tube was laid into a hori-
zontal tube fur*ce heated with a silicone 1' Uld which
was forced in from a Vobser (sic) thermostatl?see dia-
gram). The nitrogen current passing through the tube
carried the vapors of the antioxidant from the heated tube
section into an attached trap immersed into a cooling
mixture. The antioxidant condensing in the trap was quan-
titatively determined with the colorimetric method. The '
volatilization process was studied at temperatures above
100 C., The rate of volatilization of the antioxidant
was determined with respect to the velocity of the nitro-
gen current passing over the plate, to the plate thick-
ness and to the initial concentration of the ingredient.
The activation energy of the volatilization process is

allowed to age in the air-and in nitrogen for a period of 10-20 days, at tempera-

rubbers and the magnitude -of their residual deformation were determined. It
?was found that the rubbers vulcanized with thiuram as well as- with tetmehlor-

the present study showed the.accumUtion of residual deforuation proceeding

ABSTRACT: This Author Certificate presents a method for preparing stabilizers of raw
and vulcanized rubber. The method involves alkylation of the hydroquinone-p-phenylm
diamine molecular compound at 150-180C and 110-160 atm. Such ketones as acetone or
2-butanone are used as alkylation agents. Alkylation is conducted in the presence of
palladium sulfide and glacial acetic acid. (BO

TEXT: The author stresses the practical significance of fRam-r,ubbe.r
products, particularly in the manufacturing of automobile and aircraft seats,
furniture, etc. Prior to 1957, the production of foam rubber articles in
the USSR was in the initial stages, the Leningrad Rubber Article Plant being
the only manufacturer. Its productiori output was 45-50 tons per yearn After
briefly outlining the shortcomings of the previous production methods in this
field, the author describes the steps taken to enlarge the industry. The
organization of mass production was divided into 3 stagesi 1) The Balanda
Plant was opened for the production of foam rubber goods needed for the
ITM-o"s7vich" Automobile Plant. The technology was adopted from the Leningrad
Plant. The Balanda Plant was the center for research of NIIR. The produc..

the foam rubber production. Drying apparatus and an automatic latex-mixing

Hot Forging In Closed Dies Without Flash 564
COVERAGE: This booklet describes hot forging processes without flash
as used by a Leningrad machine-building plant. This method is
reported to have been successfully introduced by the machine-
building plant of the Ministry of Aviation in Leningrad for the
purpose of forging steel parts in closed dies without flash. The
author claims that forging without flash is more efficient and
economical, because trimming operations are avoided and no metal
is wasted. Pneumatic and steam hammers as well as screw presses
can be used in this process. There are numerous drawings illus-
trating the various forging presses and dies. No personalities
are mentioned. There are no references.

ABSTRACT: The progressive significance of seamless die-forging (SF)
of steels and nonferrous alloys is demonstrated by citing instances
in which this method was commercially adapted in the production
of forgings (F) shapcd as bodies of revolution: lids, plate-like
valve discs, syringe tips, as well as F's with an elongated form:
coupling pins, and blanks for screws. In order to extend success-
fully the range of application of the SF method, tile following
factors must be observed: a) the design of F's must be improved
so as to ensure proper filling in of the dies with the material
undergoing deformation; b) the blanks (13) must be pre-shaped

c) precise and clean cutting of B'S MUSt be C11SUred by en-1ploying
a multi-strip electrolytic -mechanical cutting stand capable of
cutting several B's simultaneotisly; d) contact and induction heat-
ing must be adapted in place of the flaine-heating method; e) dies
must be so designed as to guide the flow of excess n-ietal; f) high-
powered crankshaft punch presses must be constructed so as to
permit disassembly of dies in two different planes, and be equipped
with removal devices and hydraulic safety devices, which, in con-
junction with a built-in force-measuring apparatus, would prevent
overload conditions. It is most important that the greatest number
of production personnel become acquainted with the method of SF,
its advantages, and Peculiarities.

93-SOO).-The effects of various factors, particularly
soil humidity and the amount of prior moistening of the seeds,
germination of sugar-beet seeds were studied and a method
of determining 6e germinating power of )eeds in the most favourable
standard conditions was devised. Ile conditions defined for Mis
method are: temp. 20*, soil humidity 60-70%. of max. water
Lp t . In these. conditions, germinative energy is determined
:
tterm days and germinating powes atter 10 days. Preliminary
moistening of seeds prior to germination is not advisable except in
cases of necessity. (From French summary.) J.S.-,
