Abstract

The use of the deterministic model of chain growth for the copolymerization of vinylidene fluoride and hexafluoropropene instead of the classical Markov model makes it possible to correctly relate the data of the 19F NMR spectra of copolymers with different compositions to the mechanism of formation of macromolecules. The possible mechanism of copolymerization in the proposed model description involves the coordination of the radical center of the growing chain on the double bond of a monomer with subsequent incorporation of the monomer unit into the polymer chain. Although the proposed model disregards the orientation of monomer units along the chain, it properly describes the experimental data and provides an idea of the alternation of units in the copolymer at different copolymer compositions.
