REACTIVITY OF PERFLUORALKYL(METH)ACRYLATES IN RADICAL COPOLYMERIZATION WITH SOME VINYLCONTAINING MONOMERS AND PROPERTIES OF THEIR COPOLYMERS

The reactions of co-polymerization of perfluoroalkyl(meth)acrylates (n (i)F(M)A)) with MMA, styrene and dimethylvinylethynilcarbynol (DVEC) i n mass, in benzoyl peroxid (BPO) presence are studied using GLC,NMR-H' spectroscopy high resolution, UV-and IR-spectroscopy and dilatometry. Constants of copolymerization r(ij) and r(ji), distribution of homo- and helerodiades in macromolecular chain and copolymerization speed ar e determined using data of composition of co-polymers. Quantum chemica l parameters of vinyl groups of perfluoroalkyl(meth)acrylates in radic al co-polymerization with the above-mentioned monomers on the basis of received results is determined. The optical, thermomechanical propert ies and thermo-oxygenational stability of the obtained co-polymers are studied. The dependence of these properties on structure of n(i)F(M)A and their molar ratio in the reaction mixture and conditions of react ions are established.
