1. poly (arylene sulfide) resin composition, it comprises(A) polyarylene sulfide resin of 100 weight parts, the nitrogen element content that is wherein had is 0.55g or still less with respect to every 1kg resin;

  • With(B) mineral filler of 5 to 400 weight parts,Wherein said (A) polyarylene sulfide resin or its part are a kind of by the prepared polyarylene sulfide resin that obtains of the method that comprises step (1) and (2);

    (1) dehydrating step comprises, organic amide solvent and sulfur-bearing source alkali metal hydrosulfide are added in the reaction vessel, and heated mixt is removed at least a portion watery distillate from mixture system then;

    With(2) polymerization procedure;

    Comprise;

    The mixture that to after dehydrating step, stay in the system mixes to make polymerization reaction mixture with dihalogenated aromatic compounds mutually;

    The heated polymerizable reaction mixture makes sulphur source and dihalogenated aromatic compounds generation polymerization, in polymerization reaction mixture, is added into alkali metal hydroxide simultaneously continuously or off and on, makes in its scope that in polymerization procedure, remains on 7-12.5 with the pH value of controlled polymerization reaction mixture.
