Poly(methylphenylsilylene)-block-polystyrene copolymer prepared by the use of a chloromethylphenyl end-capped poly(methylphenylsilylene) as a macromolecular initiator in an atom transfer radical polymerisation of styrene

摘要

Block copolymers of poly(methylphenylsilylene) and poly(styrene) have been conveniently synthesised by using alpha,omega-di((chloromethyl)phenylethyl-dimethylsilyl)poly(methylphenylsi lylene) as a macromolecular initiator for the bulk polymerisation of styrene in an atom transfer radical polymerisation reaction. Where appropriate, the structures of the precursor and the block copolymers have been confirmed using size exclusion chromatography and NMR spectroscopy. (C) 1998 Elsevier Science Ltd.
