摘要：
A synthetic route for graftcopolymers with macroinitiators synthesized by free radical polymerization in emulsion and polyisobutylene side arms is described. Unsaturated macroinitiators can be obtained by copolymerization of dienes with styrene and a styrene-based derivatives. The resulting macroinitiators poly(styrene-co-2-acetoxy-2-(4-vinylphenyl) propane-co-butadiene) and poly(styrene-co-2-acetoxy-2-(4-vinylphenyl)propane-co-isoprene) were used to initiate the cationic homopolymerization of isobutylene. The macroinitiators and the graftcopolymers were characterised with common methods such as NMR, IR and GPC.
