A thermoplastic resin composition comprising (I) from 40 to 98 parts by weight of a thermoplastic resin comprising (A) from 10 to 90% by weight of an imidemodified copolymer obtained by reacting a composition consisting of a polymer and a primary aromatic amine to a polymer prepared by copolymerizing (a) a monomer mixture comprising an aromatic vinyl monomer, an unsaturated dicarboxylic acid anhydride and a vinyl monomer copolymerizable therewith, to (b) a rubber polymer component, to convert from 80 to 100 mol % of acid anhydride groups in the polymer to imido groups; (B) from 10 to 90% by weight of a graft copolymer prepared by copolymerizing (a) a monomer mixture comprising an aromatic vinyl monomer, a vinyl cyanide monomer and a vinyl monomer copolymerizable therewith, to (b) a rubber polymer component; and (C) from 0 to 80% by weight of a copolymer prepared by polymerizing an aromatic vinyl monomer, a vinyl cyanide monomer and a vinyl monomer copolymerizable therewith; and, (II) from 2 to 60 parts by weight of at least one fiber selected from the group consisting of glass fiber, carbon fiber and aramide fiber.

Thermoplastic resin composition

A thermoplastic resin composition comprising:

Thermoplastic resin composition containing an imide polymer and graft

In the emulsion polymerization of a monomer mixture comprising an aromatic vinyl compound, a vinyl cyanide compound and if desired, other vinyl compounds copolymerizable therewith in an aqueous medium, the vinyl cyanide compound is further added to the polymerization system in a controlled velocity during the substantial period of polymerization from the initial stage. When the copolymer thus obtained is incorporated into, for example, an acrylonitrile-butadiene-styrene terpolymer composition, thermoplastic resin compositions not coloring upon molding are obtained with a good impact resistance and heat resistance.

Thermoplastic resin compositions

An aromatic polymer is prepared by polymerizing a diphenolate compound, of a dialkali metal salt of a diphenol with a dihalodiphenyl compound, of a dihalogenobenzenoid compound having an electron withdrawing group in at least one of the positions ortho or para to each of the halogen atoms, at 200.degree. C. to 400.degree. C. in the presence of from 0.1 to 30% by weight of an inert nonpolar aromatic reaction lubricant.
