摘要：

The polyisobutylene (PIB) macromonomer having methacryloyl function was prepared from a hydroxy-terminated PIB, alpha-phenyl-omega-(2-hydroxy-1-methylethyl)-poly(1,1-dimethylethylene) and methacryloyl chloride in the presence of triethylamine. The macromonomer was polymerized by various anionic initiators to form stereoregular polymacromonomers. The polymerization of the macromonomer with t-C4H9MgBr and n-C4H9Li in toluene gave isotactic polymacromonomers. On the other hand, syndiotactic-rich polymacromonomers were obtained in the polymerizations with 1,1-diphenylhexyllithium in tetrahydrofuran and with t-C4H9Li/(C2H5)3Al in toluene.
