A resin composition, which is very highly electroconductive, comprises a vinylaromatic copolymer containing an unsaturated dicarboxylic acid anhydride and a metallic filler. It is also improved in mechanical properties.

Highly conductive styrenic resin composition

A resin composition is resistant to heat and impact and comprises (a) a polyphenylene ether resin, (b) a rubber graft copolymer resin obtained from a rubbery polymer having a glass transition temperature of 0.degree. C. or lower, an aromatic vinyl monomer and an alpha, beta-unsaturated dicarboxylic anhydride monomer and (c) a block copolymer of an aromatic vinyl monomer and an aliphatic diene monomer. It may contain a mono-olefinic monomer having a nitril or carboxylic ester group as the rubber graft copolymer resin.

Heat- and impact-resistant resin composition

Heat-resistant, high-impact thermoplastic resin compositions comprising a graft copolymer (A) obtained by graft-copolymerizing an aromatic vinyl compound and an unsaturated carboxylic acid anhydride onto a rubbery polymer; a composite modifier (B) obtained by graft-copolymerizing an aromatic vinyl compound and a methacrylate ester monomer onto a diene rubber polymer; and an aromatic polycarbonate resin (C).

Heat-resistant, high-impact resin composition

A process for preparing a thermosetting organopolysiloxane which is soluble in an organic solvent, comprising subjecting to a hydrolyzing condensation reation one or a mixture of two or more alkoxysilanes having the formula
