    • PROBLEM TO BE SOLVED: To provide a PAS (polyarylene sulfide) resin excellent in a thermal property and improved in brightness.SOLUTION: The present invention relates to a polyarylene sulfide resin, saying in detail, the polyarylene sulfide resin produced by a method for producing a polyarylene sulfide resin including: (a) a step of fusion-mixing a composition containing solid sulfur, an aryl iodide compound and a polymerization inhibitor, (b) a step of polymerization-reacting a fused mixture in the step (a) for 1-30 hours, while changing a reaction condition from an initial reaction condition of 180-250°C of temperature and 50-450 Torr (6.7-60.0 kPa) to a final reaction condition of 270-350°C of temperature and 0.001-20 Torr (0.0013-2.7 kPa), and (c) a step of heating a reaction mixture in the step (b) at 270-350°C of temperature for 1-25 hours.
    • 要解决的问题:提供热性能优异且亮度提高的PAS(聚芳硫醚)树脂。 聚芳硫醚树脂本发明涉及一种聚芳硫醚树脂,详细说明了通过聚芳硫醚树脂的制造方法制造的聚芳硫醚树脂,其包括:(a)将含有固体硫的组合物, 芳基碘化合物和阻聚剂,(b)使步骤(a)中的熔融混合物聚合反应1-30小时的步骤,同时从180-250℃的初始反应条件改变反应条件, 温度和50-450乇(6.7-60.0kPa),至270-350℃的温度和0.001-20乇(0.0013-2.7kPa)的最终反应条件,和(c)加热反应混合物的步骤 步骤(b)在270-350℃的温度下进行1-25小时。 版权所有(C)2013,JPO&INPIT
