Modifications of Polysilanes and Polysilane Copolymers

Pagination or Media Count:
Polymethylphenylsilylene has been functionalized by protodearylation with trifluoromethanesulfonic acid. Comb-like graft copolymers have been prepared by polymerizing tetrahydrofuran, 2-methyl-2-oxazoline, and isobutylvinyl ether from a partially triflated polymethylphenylsilylene 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.
