Outline of Final Research Achievements

Radical polymerization of macromonomer containing well-defined hyperbranched polyamide (HBPA), which was synthesized by chain-growth condensation polymerization of AB2 monomer, followed by modification of the focal point, was studied. During this research period, we have revealed that graft polymer with high molecular weight and low polydispersity was obtained when the polymerization with 2,2'-azobis(4-methoxy-2.4-dimethylvaleronitrile) at 30 ℃.
