Polyphenylene sulfide resin composition.

摘要

A polyphenylene sulfide resin composition improved in the impact strength, toughness, high temperature resistance and solvent resistance properties is disclosed. The composition comprises (A) 60 - 99.5% by weight of a thermally cured polyphenylene sulfide material having a melt viscosity of 500 - 30,000 poises and which has been derived, by thermally curing, from a polyphenylene sulfide having a melt viscosity of 400 poises of higher and containing 0.05 - 5 mol% of amino groups on the basis of the phenylene sulfide repeating units, and (B) 40 - 0.5% by weight of a modified polyethylene material comprising at least one polyethylene onto which at least one unsaturated carboxylic acid and/or derivative thereof is graft-copolymerized in a proportion of 0.1 - 10% by weight of the total weight of said modified polyethylene material. i
