抄録

Hybrid organic－inorganic polymers were synthesized through hydrosilylation of 1,3,5,7-tetramethylcyclotetrasilox ane (TMCS) and divinyl-terminated tetramethylsiloxane (DTMS) monomers. Controlling the hydrosilylation reaction by varying the feeding ratio as well as the total monomer concentration, chemically-soluble TMCS－DTMS hybrid polymers were obtained as a liquid state. The resulting polymer was colorless and viscous liquid, seemingly took linearly elongated structures without no remarkable gel-form. Unreacted Si－H groups remained in the polymer, which allowed network formation of the TMCS－DTMS hybrid polymer with various crosslinkers such as DTMS, divinylbenzene (DVB), 3,3’-divinylbiphenyl (DVBP), and di(ethyleneglycol) divinylether (DEG). Consequently, transparent and thermally stable hybrid networked polymer films with a thickness of ca. 0.2 mm were prepared through hydrosilylation and self-condensation reaction under curing process, which was proved using FT－IR spectroscopy.
