A polyphenylene sulfide resin composition includes a polyphenylene sulfide resin (A); an aromatic vinyl compound block copolymer (B) containing at least one functional group selected from the group consisting of a carboxyl group, an acid anhydride group, a hydroxyl group, an amino group, an epoxy group and an isocyanate group; and an alkoxysilane compound (C) containing at least one functional group selected from the group consisting of an epoxy group, an amino group and an isocyanate group; wherein a phase structure of the polyphenylene sulfide resin composition is a sea-island structure in which the polyphenylene sulfide resin (A) forms a sea phase, and the aromatic vinyl compound block copolymer (B) forms an island phase dispersed in a number average dispersed particle size of 1,000 nm or less.

Polyphenylene sulfide resin composition, method of producing same, and molded article

A polyphenylene sulfide resin composition includes (A) 100 parts by weight of an acid-treated polyphenylene sulfide resin, (B) 10 to 100 parts by weight of a glass fiber, and (C) 0.1 to 10 parts by weight of an amino group-containing alkoxysilane compound, wherein the polyphenylene sulfide resin composition has an exothermic peak temperature (Tmc) of 195&#xb0; C. to 225&#xb0; C., the exothermic peak temperature being observed during a crystallization caused when the polyphenylene sulfide resin composition is melted by heating to 340&#xb0; C. and then cooled at a rate of 20&#xb0; C./minute, using a differential scanning calorimeter.
