摘要：

Polystyrene/poly(methylphenylsilylene) and polyisoprene/poly(methylphenylsilylene) block copolymers were prepared by two independent methods. Subsequent additions of solutions of cyclotetrasilanes in benzene to the living ends of polystyrene and polyisoprene resulted in the formation of well-defined block copolymers with narrow molecular weight distributions (M(w)/M(n) < 1.3). Condensation of the living ends of polyisoprene and polystyrene with bromide end-terminated polysilanes also resulted in the formation of block copolymers. The materials were characterized by H-1 and Si-29 NMR, GPC, DSC and elemental analysis.
