THERMAL DECOMPOSITION OF THE PEROXIDE BONDS IN POLYMERS

Abstract

Peroxide-containing polymers containing diacyl peroxide groups in the main chain and in the side parts of macromolecules were obtained. The thermal decomposition of peroxide groups in macromolecules is well described by the first-order kinetic equation of rate. During the decomposition of O–O groups of polymers containing peroxide groups in the main chain, a decrease in the degree of polymerization of polymers is observed. The solvent in which the process takes place and the nature of the polymer-matrix, which contains peroxide groups, affects the rate of decomposition of peroxide groups and the degree of degradation of polymer macromolecules. Peroxide-containing polymers can be successfully used to obtain block copolymers, crosslinking agents, and macromolecular initiators.
