Synthesis and Characterization of Gradient Copolymers Composed of Methyl Acrylate and p-Chlorostyrene Via Atom Transfer Radical Copolymerization

摘要

@@Gradient copolymers are defined as copolymers of two or more monomers whose composition profilevaries along the chain reflecting variation in monomer concentrations as conversion proceeds1. They can beconveniently synthesized by spontaneous polymerization using ATRP method and there are several reportsof this method to synthesize gradient copolymers successfully2,3. However, as far as we know, there isalmost no research about characterization of gradient copolymers.
