Polymerization of acrylamide by the redox system cerium(IV) with poly (ethylene glycol) with azo groups

Abstract

Abstract Polymerization of acrylamide using Ce(IV) with poly(ethylene glycol) having azo and hydroxyl functions, was carried out to yield acrylamide-(ethylene glycol) block copolymers with labile azo linkages in the main chains. These prepolymers were used to induce the radical polymerization of acrylonitrile and acrylamide through the thermal decomposition of the azo group, resulting in the formation of multiblock copolymers.
