Abstract
A diblock copolymer consisting of poly(methyl methacrylate) (PMMA) and poly(vinyl acetate) (PVAc) with hydroxyl group at one end is prepared by successive charge transfer polymerization (CTP) under UV irradiation at room temperature using ethanolamine and benzophenone as a binary initiation system. The diblock copolymer PMMA-b-PVAc could be selectively hydrolyzed to the block copolymer of poly(methyl methacrylate) and poly(vinyl alcohol) (PVA) using sodium ethoxide as the catalyst. Both copolymers, PMMA-b-PVAc and PMMA-b-PVA, are characterized in detail by means of FTIR and 1 H NMR spectroscopy, and GPC. The effect of the solvent on CTP and the kinetics of CTP are discussed.
