TITLE: Chemical plasticizing of polymers. I. Chemical plasticixing~Gf nitro-
cellulose by the implantation of polymethaerylate

ABSTRACT: Using Ce(NH4)2(NO3)6 as the oxidizing and nitrocellulose as the reducing
agent, the authors prepared a series of grafted copolymers containing 7.15-95.0%
,nitrocellulose and 5.0-28.5% polymethacrylate; the maximal polymethacrylate content
was obtained in 2 hours. These copolymers were then compared with corresp6nding
mixtures of nitrocellulose and polymethacrylate homopolymers with respect to their
thermomechanical and dynamometric, properties. The results -shown in Figs. I and 2
of the Enclosure indicate that the plasticizing effect resulting from the implants-

tion of elastic polymer 'chains into the macromolecules of a rigid polymer is equal
to that produced by physical addition of low-molecular-weight plasticizers. The
only advantage of chemical plasticizing is the higher value of the modulus of
elasticity in the copolymer. Orig. art. has: 2 tables and 4 graphs,

TOPIC TAGS: polymer,, copolymer, graft copolymer., multilayer copolymer, dacron,

ABSTRACTI : The authors found it possible to graft repeatedly certain vinyl monomers
to,polymers, thus obtaining the so-called "poiaosor" (repeatedly grafted) copolymers.
The pemosors obtained in this manner have a high molecular weight and are not of

sol. The authors used dacron and caprono as the base and grafted. thereon (repeat-
