Title: Controlled Radical Copolymerization of N-(4-Hydroxyphenyl) Maleimide and Styrene Based on RAFT Process
Abstract: Copolymerization of N-(4-carboxyphenyl) maleimide with styrene was introduced in tetrahydrofuran by taking S-benzyl dithiobenzoate as a RAFT reagent.Results show that the number average molecular weight of the obtained copolymers increases linearly with the increase of the monomer conversion and the distributions of the copolymers are less than 1.5,showing that the RAFT regent S-benzyl dithiobenzoate possesses a good ability to control the copolymerization of N-(4-carboxyphenyl) maleimide with styrene.Investigations of the copolymerization at different temperatures gave the apparent activation energy about 1.39 kJ/mol.
