A Tandem Approach to Graft and Dendritic Graft Copolymers Based on “Living” Free Radical Polymerizations

Abstract

Owing to their inherent differences, consecutive “living” free radical polymerizations can yield graft and dendritic graft (dendrigraft) copolymers with multiple chain-end functionalities such as that shown schematically on the right (PS = polystyrene), PBMA = poly(n-butyl methylmethacrylate). The first polymerization leads to the linear backbone, and subsequent polymerizations introduce grafted chains.
