Polymerization of monomers containing functional silyl groups. 11. Anionic living polymerization of 3-(tri-2-propoxysilyl)propyl methacrylate

Anionic polymerizations of 3-(trimethoxysilyl)propyl, 3-(triethoxysilyl)propyl and 3-(tri-2-propoxysilyl)propyl (3) methacrylates were investigated in THF at -78°C using various initiators. The polymerization of 3 proceeded well to give poly(3) quantitatively with each of the initiators except for LiAlH 4 . A living polymerization is observed using the 1,1-diphenylhexyllithium/LiCl initiator. A novel well-defined block copolymer poly(3-methyl methacrylate) was prepared by sequential anionic polymerization
