Silicon Chemistry

Abstract

Spirocyclosiloxanes have been prepared by insertion of 0=Si=0 under flash vacuum pyrolysis conditions into silicon-oxygen single bonds of cyclic siloxanes. We have prepared several new types of silicon containing polymers. 1, 3-Adamantyldimethylsiloxane copolymers have been prepared. These polymers are quite thermally stable. This may result from steric hindrance to the reversion reaction provided by the adamantane nucleus. Four novel types of unsaturated silyl substituted polymers have been prepared. Stereo-and regio-specific anionic polymerization of 2-trimethylsily-1,3-butadiene has been achieved.
