Phenyl-vinyl-oligosiloxane (PVO) has been was synthesized by nonhydrolytic sol-gel condensation process from the reaction of vinyltrimethoxysilane (VTMS) and diphenylsilanediol (DPSD). Barium hydroxide monohydrate was used as a catalyst and promotes the direct condensation reaction between the methoxy radical of VTMS and diol radical of DPSD from siloxane bonds. The 1,3,5-tris(dimethylhydrosilyl)benzene (TDMSB), crosslinking agent, was synthesized through in situ Grignard reactions of 1,3,5-tribromobenzene with chlorodimethylsilane. The synthesized PVO were thermal cured with a cross-linker, TDMSB, through a hydrosilylation reaction under a Pt catalyst, Platinum cyclovinylmethyl-siloxane complex (Pt0․[CH2=Ch(Me)SiO]4). This research was financially supported by the Ministry of Trade, Industry, and Energy (MOTIE), Korea, under the “Regional Specialized Industry Development Program” supervised by the Korea Institute for Advancement of Technology (KIAT).
