Abstract
The preparation of a block copolymer of methyl methacrylate (MMA) and vinyl acetate (VAc) (PMMA-b-PVAc) was carried out by successive charge -transfer polymerization (CTP) in aniline-benzophenone as binary initi ation system under ultraviolet irradiation; subsequently a block copol ymer of PMMA and poly(vinyl alcohol) (PMMA-b-PVA) was derived by selec tive hydrolysis of PMMA-b-PVAc in ethanolic sodium ethoxide. These cop olymers were characterized in detail by means of Fourier transform inf ra-red and proton nuclear magnetic resonance spectroscopies, and gel p ermeation chromatography. The solvent polarity exerts an effect on the copolymerization. (C) 1997 Elsevier Science Ltd. All rights reserved.
