外文摘要：Chemoselective,living/controlled polymerizations of allyl methacrylate(AMA)and vinyl methacrylate(VMA)with/without methyl methacrylate(MMA)by using the phosphonium ylide/organoaluminum based Lewis pairs(LPs)have been realized.The P-ylide-2/AlMe(BHT)2(P-ylide-2=Ph3P=CHMe and BHT=2,6-iBu2-4-MeC6H2O)was demonstrated to be superior by which homopolymers PAMAs(Mn=27.6-111.5 kg/mol and Ð=1.14-1.25)and PVMAs(Mn=28.4-78.4 kg/mol and Ð=1.12-1.18)and block copolymers PMMA-b-PAMA,PAMA-b-PVMA,PAMA-b-PMMA,PMMA-b-PAMA-b-PMMA,PAMA-b-PMMA-b-PAMA,and PAMA-b-PVMA-b-PAMA were synthesized.In the polymerizations,all of the monomers were reacted by the conjugated ester vinyl groups leaving intactly the nonconjugated acryloxy groups.The pendant acryloxy groups attached to the main chain enable further to post-functionalization by the AIBN-induced radical"thiol-ene"reaction using PhCH2SH.The thiolether side group-containing polymers PAMA-SCH2Ph and PAMA-SCH2Ph-b-PMMA-b-PAMA-SCH2Ph were thus prepared.
