Patent ID: 7250469

Claim:
A resin molded product by melt molding of a polyphenylene sulfide resin composition, said polyphenylene sulfide resin composition comprising: (a) 60% by weight to 95% by weight of polyphenylene sulfide resin, and (b) 5% by weight to 40% by weight of an olefin resin; said (a) polyphenylene sulfide resin comprising: (a-1) 100 parts by weight of a polyphenylene sulfide resin that is not cross-linked by thermal oxidation and having a melt flow rate (315.5° C., 5000 g load) of 90 g/10 min to 350 g/10 min measured according to ASTM-D1238, and an amount of extracts by chloroform of 2.2% by weight to 4.5% by weight, and (a-2) 5 parts by weight to 80 parts by weight of a polyphenylene sulfide resin having a melt flow rate (315.5° C. 5000 g load) of 50 g/10 min to 800 g/10 min measured according to ASTM-D1238 and an amount of extracts by chloroform of not higher than 1% by weight and being not cross-linked by thermal oxidation; and said (b) olefin resin comprising a mixture of: (b-1) an olefin copolymer prepared by introducing an epoxy group-containing monomer component into an olefin (co)polymer, and (b-2) an ethylene-α-olefin copolymer prepared by copolymerizing 15% by weight to 35% by weight of ethylene and 65% by weight to 85% by weight of α-olefin containing 3 to 16 carbon atoms; and said polyphenylene sulfide resin composition having a melt flow rate (315.5° C., 5000 g load) of 15 g/10 min to 50 g/10 min measured according to ASTM-D1238.
