Abstract

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-

/AlMe(BHT)

(P-ylide-

=27.6−111.5 kg/mol and

=1.14−1.25) and PVMAs (

=28.4−78.4 kg/mol and

=1.12−1.18) and block copolymers PMMA-

-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 PhCH

SH. The thiolether side group-containing polymers PAMA-SCH
