PURPOSE:To provide a resin compsn, having excellent blend compatibility and improved impact resistance, containing a block copolymer composed of a polyphenylene sulfide moiety and a polysulfone moiety. CONSTITUTION:A resin compsn. consists of a block copolymer composed of a polyphenylene sulfide moiety and a polysulfone moiety and polyphenylene sulfide and/or polysulfone and optionally a filler, said polyphenylene sulfide to be used as an ingredient for said block copolymer and to be mixed with said copolymer is composed of pref: at least 70 mol % of a structural unit of the formula, because such polyphenylene sulfide gives a compsn. having excellent characteristics. Polyphenylene sulfide has a longarithmic viscosity [eta]of pref. 0.03-0.80. |
