    摘要: Upstaged compositions are prepared by the reaction in the presence of a triarylphosphine catalyst between at least one bisphenol polyglycidyl ether, at least one epoxidized novolak and at least one brominated bisphenol. They may be used for the preparation of resinous blends with polyphenylene ethers, which, in combination with further components, may be used in the preparation of laminates useful as printed circuit boards and having excellent physical and electrical properties.

    摘要: Blends of high molecular weight polyphenylene ethers with various epoxy materials, particularly polyglycidyl ethers of bisphenolic compounds, are homogeneous at high temperatures and may be cured in the presence of a catalyst such as aluminum tris(acetylacetonate) or zinc bis(acetylacetonate), especially in the additional presence of an accelerator such as a basic nitrogen compound. The cured compositions have advantageous physical and electrical properties and are useful, for example, for the preparation of printed circuit boards.

    摘要: Photopatternable silicone polyamic acid can be spun onto a substrate and thereafter used in combination with a photoresist as an antireflective coating or as a patterned silicone polyimide. The silicone polyamic acid can be used with an absorbing dye, or it can be tinted with an organic dye to provide color filters when applied on a transparent substrate.

    摘要: A method is provided for making siloxanenorbornane bisanhydride. Norbornane anhydride is initially hydrosilylated with dimethylchlorosilane in the presence of a platinum catalyst. The resulting dimethylchlorosilyl norbornane anhydride is thereafter hydrolyzed while in the molten state.
