    • A polyarylene sulfide resin composition comprising a polyarylene sulfide (A) and an alkaline earth metal organic carboxylate (B) in an amount of 0.001 to 10 mol% based on the formula -(Ar-S)-, a repeating unit of polyarylene sulfide, wherein the polyarylene sulfide (A) has a weight average molecular weight of 10,000 or more and a weight reduction during heating that satisfies the following equation. ”Wr = W 1 ˆ’ W 2 / W 1 × 100 ‰¤ 0.18 % In the equation, ”Wr is a weight reduction ratio (%) determined by a thermogravimetric analysis performed in a non-oxidizing atmosphere under normal pressure at a temperature rise rate of 20°C/min from 50°C to any temperature equal to or higher than 330°C, wherein W 1 is a sample weight at 100°C, and W 2 is a sample weight at 330°C. Provided is a polyarylene sulfide resin composition that contains a polyarylene sulfide produced in an economical and simple manner, has a lowered melt crystallization temperature and a retarded solidification rate, and generates little amount of gas at high temperatures.
    • 一种聚亚芳基硫醚树脂组合物,其特征在于,相对于式( - Ar-S) - ,含有0.001〜10摩尔%的聚芳硫醚(A)和碱土金属有机羧酸盐(B),聚芳硫醚的重复单元, 其中,聚芳硫醚(A)的重均分子量为10,000以上,加热时的重量减少量满足下式。 “Wr = W 1'W 2 / W 1×100‰·0.18%式中,Wr是通过在非氧化性气氛下常压下,在温度下进行的热重量分析测定的重量减少率 从50℃到任意温度为330℃以上的升温速度为20℃/ min,W 1为100℃下的试样重量,W 2为330℃下的试样重量。 本发明提供一种聚芳硫醚树脂组合物,其含有经济且简单地制造的聚芳硫醚,熔融结晶化温度低,凝固速度慢,在高温下产生的气体量少。
