Disclosed are a polyphenylene sulfide composition having excellent impact characteristics, melt flow characteristics and flexibility which comprises, as indispensable components, (A) a polyphenylene sulfide, (B) an epoxy group-containing olefinic polymer, and (C) at least one elastomer selected from ethylene/propylene copolymers, ethylene/butene copolymers, ethylene/propylene/diene copolymers, hydrogenated styrene/butadiene/styrene block copolymers, copolymers of ethylene with a monomer selected from acrylic acid, methacrylic acid and alkyl esters and metal salts thereof, and polyamide elastomers; and a shaped article made from the polyphenylene sulfide composition.

Polyphenylene sulfide composition and shaped articles made therefrom

Disclosed is a polyphenylene sulfide resin composition having a superior heat resistance and impact resistance obtained by melt-kneading a modified polyphenylene sulfide resin obtained by reacting a polyphenylene sulfide resin with a carboxylic acid anhydride, with at least one thermoplastic resin selected from a polyamide resin, a polyester resin, a polycarbonate resin, a polysulfone resin, and a polyamide-imide resin.

Polyphenylene sulfide resin composition

The thermoplastic aromatic polyamideimide compolymers comprising the structural units (1), (2) and (3) represented by formulae, ##STR1## respectively, (2) and (3) being at ratio of 1 mole to 1 mole of (1), (3) being at a ratio of 0.95-0.05 mole to 0.05-0.95 mole of (2), (1) and (2) or (3) being alternatively interconnected and Ar and Ar' being composed of 5 to 70 mole % of ##STR2## and 95 to 30 mole % of ##STR3## provide the moldings being superior in heat stability and fluidity at the temperatures of 300.degree. to 400.degree. C. and injection moldable and having desired characteristics.

Thermoplastic aromatic polyamideimide copolymer from polyamide diamine

Polyimide prepolymers having excellent heat resistance can be prepared in one stage by the reaction of polyamines and aromatic double bond-containing dicarboxylic acids or derivatives thereof in the presence of oxide compounds of phosphorus without isolating any intermediate in the course of said reaction.

Method of preparing polyimide prepolymer from ethylenically unsaturated

Thermoplastic polyamide imide copolymers are provided which are excellent in both heat stability and melt viscosity characteristics at a temperature of from about 300.degree. C. to about 400.degree. C., and method of preparation.
