Abstract:
A composition and method for making a silicone composition is provided which comprises at least one polysiloxane or silicone resin containing at least one linker and either one or two molecular hooks.
Abstract:
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.
Abstract:
The instant invention relates to a novel process for the hydrolysis of the by-products produced during the manufacture of methyldichlorosilanes comprising combining the by-products with an aqueous medium, optionally comprising a surfactant, at a pH range of at least about 7 and at a temperature of above about 0.degree. C. to produce a solid material in which copper and other metals are retained in a solid phase thereby resulting in a product with a high copper content.
