Graft Polymerization of Styrene onto Chlorinated Polyethylene Having Acrylamide Pendants

Abstract

Chlorinated polyethylenes having acrylamide units as pendants (CPE-AAm, degrees of substitution=8.5 and 15.5) were prepared by the reaction of chlorinated polyethylene (CPE) with acrylamide using amines as catalysts. Grafting in the graft polymerization of styrene onto CPE-AAm with AIBN as initiator was higher than that in the graft polymerization of styrene onto CPE polymer without acrylamide residues. At the concentration 2 mol/l of styrene, grafting for CPE-AAm was about 10 times as large as the value for CPE.
