Synthesis and characteristic of double hydrophilic block copolymer with amine pendant chains

Novel double hydrophilic block copolymers with amine pendant chains were synthesized by polymerization of 4-vinyl benzylamine hydrochloric salt using 4,4′-azo-bis[4-cyanopentanoate poly(ethylene glycol) ester] as macroazoinitiator. The structures of the copolymers were characterized by 1H NMR, FTIR spectra and acid-base titration, GPC-MALS techniques.
