摘　　要：本文研究探讨了不同端基调节剂对聚苯硫醚(PPS)树脂实施端基处理后对其反应活性及熔融结晶温度(Tc2)的提升。通过对比分析,发现以含羟基芳香族硫醇化合物为端基调节剂时,PPS树脂的反应活性和Tc2提升更明显。后续洗涤纯化过程中增加酸洗步骤,可以进一步促进树脂反应活性与Tc2的提升,对于优化共混改性挤出过程中复合材料的整体性能尤为关键。In this paper,the enhancements in reaction activity and melt crystallization temperatures(Tc2)of poly(phenylene)sulfide(PPS)resin following end-group modification with different terminal modifiers are examined.Through comparative analysis,it is found that PPS resins dis-play notably more significant improvements in both their reaction activity and Tc2 when subjected to end-group adjustment with hydroxyl-terminat-ed aromatic thiol compounds.The reaction activity and Tc2 of PPS resin are facilitated an increased promotion via an acid washing treatment in the subsequent purification process.This is particularly critical for optimizing the overall properties of composites in the process of blending modified extrusion.
