Diacetylenic polyorganosiloxanes, intermediates therefor, and cured compositions prepared therefrom |
摘要 |
Intermediate compositions comprising ethynylorgano polyorganosiloxanes are prepared by hydrosilylation of an olefinic hydroxy compound followed by reaction with a propargyl halide, or by hydrosilylation of a diethynyl compound. The intermediate compositions may be oxidatively coupled to form poly(conjugated diacetylenic)polyorganosiloxanes. The latter may be cured thermally or by radiation to form cured compositions useful as release coatings or conformal coatings.
