PROBLEM TO BE SOLVED: To obtain a polyphenylene sulfide resin composition having excellent toughness, impact resistance, weld strength and molding processability together. SOLUTION: This polyphenylene sulfide resin composition comprises (a) 67-98.8 wt.% polyphenylene sulfide having 200-20,000 poise melt viscosity and substantially not thermally oxidized and cross-linked, (b) 0.1-3 wt.% polyfunctional isocyanate and (c) 1-30 wt.% maleic anhydride containing ethylenic copolymer. |
