influences the reaction rate, but that the selective behavior

respond with the publications available in this field (Hof 2).
From among all factors Investigated the intensity of the sizing
of the solution and the percentage of the quantity of the
medium exert a noticeable influence upon the selectivity of
the reaction* At a low intensity the'reaotion did not proceed
selectively* In the alcohol solution with the pH > 7 the re-
action proceeded more rapidly but with less selection than In
acid and neutral medium, The determined hydrogenation character
of the dissolved vinyl'aostylene in the presenoe of the pal-
ladium catalyst as well as the determined dependen" of tb*
selective behavior of the process on the intensity of the.
mixing of the solution completely agree with the absorption
theory concerning the catalytlo hydrogenation (Ref 4).

ABSTRACT: The study deals with the comparison or the reactivity
constants or solution copolymerization and emulsion
copolymerization or chloroprene with hexarluorobutadiene,
and with the characteristics or copolymers thus obtained.
The experimental part was described-prevlously by the
authors (in thid journalo 1959, Vol 321 Nr 9). Esteramine
(eater or diethylamInoethanol and lauric acid) was found to
be the most suitable emulsifying agent, at an optimum-con-
centration of 5%. The rate of polymerization Increased
with the acidity of the water phace; the optimum value was
PH.- 3. The optimum ratio of the water phase of the mono-
Imer mixture was 2*1. Among copolymerization catalysts,
IK S 0 was the mo;t effective. The rate of p;lymerization

the same value; this confirmed the authoro' a3sumption that
these constants do not depend on the manner In which the
copolymerization Is conducted. It was aloo established that
the tendency to the alternation of chloroprene and hexa-
riuorobutadlene molecules In the copolymer, as well as the
tendency of ttexarluorobutadlene molecules t'o JoIn toGether,
increased with the concentration of liexat'luorobutadiene in
the initial monomer mixture. Copolymers of hexafluoro-
butadiene with fluoroprene, Isoprene, and chlovoprene
vulcanized at a high rate. It would be of Int.-ce-cst, there-
fore, to Investigate the feasibility of vulcanizing fluorin-
ated olefins by incorporation In the chain of small amounts

oxidizing effect of air on the stability of Nalrit.e to considered one of the main
factors during Its storage and vulcanization for avoiding scorching especially at
elevated temperatures, the proper selection of stabilizers acquires great signIfi-
canoe. The effect of the above-mentioned commonly-used stabilizers was described
in Refs. 2 mid 3. These stabilizers, during longer storage periods at room tem-
perature, as well as during the 'long-lasting processing of the mixtures at high

would be better and more effective inhibitors of the oxidizing processes, than
noozone D. Th.9 application of noosono D derivatives, with polar substitutes (oxy-
-group, sulfide bonds) as stabilizers, or increasing the degree of linkage (41-
phenrl- snd dinaPhthrlphonylonedlamines), does not increase the stability of Hai-
rite. It does, however, Increase Its tendency 'to scorching during thermal aging
(120 hours at TOO. Prom these observations it is concluded that the scorching
mechanism of the chloroprone polymers Is not dependent on the ox1dising processes,,
but Is due rather to the radical decay of the molecules along the polysulfide

advantages of noozons, am an oxidising Inhibitor. As to the polyphonols In the

oxide groups (lignin, dimethylphonyl-n-crosolp paraditertlarybuty1dioxyphonylono-
sulfide), -these also had a ne"tive effect on the stability of Write, incroasIng
the scorching tendencies (Via. 3). The accelerating effect of the phonols in this
