摘要：

Copolymerization of styrene with styrene-terminated polystyrene macromonomer (SSTM) by CpTiCl3-methylaluminoxane (MAO) catalyst was investigated. SSTM was prepared by a reaction of living polystyrene initiated with sec-butyllithium (s-BuLi) and p-chloromethyl styrene at -78 degrees C. The synthesized SSTM has a high terminal functionality and a narrow molecular weight distribution. Graft copolymers of polystyrene consisted of syndiotactic main chain and atactic side chain were synthesized by CpTiCl3-MAO catalyst. The synthesized graft copolymer was confirmed to have highly syndiotactic sequence on the main chain. (C) 1999 Elsevier Science Ltd. AU rights reserved.
