A method is provided for effecting the removal of cured polyurethane paint from the surface of aromatic polycarbonate blend surfaces. Effective removal of thermally cured polyurethane paint from aromatic polycarbonate blend surface can be achieved by immersing the painted aromatic polycarbonate blend in an aqueous bath containing organic solvent, an alkali metal hydroxide and a surfactant.

Method for salvaging aromatic polycarbonate blend values

Curable compositions containing a polyphenylene ether and a polyepoxide composition containing brominated and non-brominated bisphenol polyglycidyl ethers, in combination with further components including specific catalysts and hardeners, may be used in the preparation of laminates useful as printed circuit boards and bonding sheets therefor and having excellent physical and electrical properties.

Curable dielectric polyphenylene ether-polyepoxide compositions useful

Curable compositions containing a reaction product of at least one bisphenol polyglycidyl ether, at least one epoxidized novolak and at least one brominated bisphenol, in combination with a polyphenylene ether and further components including specific catalysts and hardeners, may be used in the preparation of laminates useful as printed circuit boards and having excellent physical and electrical properties.

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.

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.

Compositions comprising polyphenylene ethers, polyepoxides and aluminum

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.

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.
