Abstract

For the precision synthesis of primary amino functional polymers, cationic polymerization of a phthalimidecontaining vinyl ether monomer precursor, 2-vinyloxyethyl phthalimide (PIVE), was examined using a base-assisting initiating system. Living polymerization of PIVE In CH2Cl2 In the presence of 1,4-dioxane as an added base yielded nearly monodispersed polymers (MW/Mn < 1.1) and higher molecular weight polymers, which have never been obtained using other initiating systems. Furthermore, block copolymers with hydrophobic or hydrophllic groups could be prepared. The deprotec-tion of the pendant phthalimide groups gave well-defined pHresponsive polymers with pendant primary amino groups. Dual-stimuli-responsive block copolymers having a pH-responsive polyamine segment and a thermosensitive segment selfassembled in water in response to both pH and temperature.
