Abstract
A novel phenylenesulfide resin composition comprises PA0 (I) a poly-p-phenylenesulfide, PA0 (II) a poly-m-phenylenesulfide, and PA0 (III) a phenylenesulfide block copolymer consisting essentially of a repeating unit ##STR1## (A) and a repeating unit ##STR2## (B), wherein from 20 to 5,000 units on the average of the repeating units (A) linked together exist in the molecular chain in the form of the block component, and wherein the molar faction (X) of the repeating unit (A) is in the range of 0.10 to 0.95, the mixing ratio of the three components (I), (II) and (III) being in a specified range. The composition is characterized by compatibility between the components (I) and (II), whereby transparency, physical properties and other characteristics thereof are markedly enhanced.
