Abstract

Methyl methacrylate (MMA) and acrylonitrile (AN) block copolymers were prepared by the use of difunctional initiators such as dilithio-acetanilide (DLAC) and dilithio-trans-β-methylcinnamanilide (DLMC). MMA was polymerized first and its “living” end was deactivated, and then AN was added. Homopolymers of MMA and AN were separated from the gross polymer by the successive extractions with benzene and 50-% KSCN aqueous solution. The insoluble polymer showed a solubilization behavior of block copolymer in column fractionation. Ozonolysis of the insoluble polymer obtained with DLMC also suggested that the expected block copolymer was prepared.
