PURPOSE:To provide the titled compsn. which has excellent toughness and flow characteristics and exhibits low stress, by adding a thermoplastic fluororubber to a polyarylene sulfide resin. CONSTITUTION:100pts.wt. polyarylene sulfide resin (A) having a logarithmic viscosity of 0.03-0.8, composed of at least 70mol% of a repeating unit having the formula is blended with 0.1-60pts.wt. thermoplastic fluororubber (B) composed of a linear, branched or radial block copolymer consisting of a hard segment (a) composed of at least one fluororesin block having an MW of 2,000-500,000 and a soft segment (b) composed of at least one fluororubber block having an MW of 20,000-1500,000 in a weight ratio of (a) to (b) of 5-60/40-95 ad optionally, 0.001-10pts.wt. polymer (C) having fluoroaliph. groups and a number-average MW of 1,000-1000,000, which is a random, block or graft copolymer of an unsaturated monomer having a fluoroaliph. group (e.g., a fluoroacrylate) with an unsaturated monomer having an org. group affinitive with the component (e.g., styrene). |
