Anionic ring-opening polymerization of 1,1,2,2-tetramethyl-1,2-disilacyclohexane: homopolymerization, alternating copolymerization with 1,2-epoxycyclohexane and oxygen-abstracting polymerization with 1,2-epoxybutane

Abstract

The ring-opening polymerization of 1,1,2,2-tetramethyl-1,2-disilacyclohexane was conducted by anionic initiators; the homopoymer, the alternating copolymer with 1,2-epoxycyclohexane, and the siloxane polymer by oxygen-abstracting polymerization with 1,2-epoxybutane are produced.
