Modifications of Polysilanes and Polysilane Copolymers

摘要

Poly(methylphenylsilylene)has been functionalized by protodearylation withtrifluoromethanesulfonic acid. Comb-like graft copolymers have been prepared by polymerizing tetrahydrofuran, 2-methyl-2-oxazoline, and isobutylvinyl ether from a partially triflated poly(methylphenylsilylene) backbone. Model studies using trimethylsilyl trifluoromethanesulfonate to initiate the cationic polymerization of these organic monomers indicated that a promoter was required to achieve more efficient initiation. jg p.2.
