| Abstract: | The isobutylene cationic polymerization initiated by BC/TiCl4 was studied, the effects of initiator, co-initiator, electron donor on IB cationic polymerization was discussed, preferable reaction conditions were achieved by analyzing experimental data and GPC traces. PIB-b-PSt diblock copolymer was synthesized by sequentially adding IB and St into the BC/TiCl 4/TEA system. |
