| 摘 要： | 聚苯砜醚是一种综合性能比较好、可在180℃长期使用的热塑性工程塑料,在国内外受到一定的重视。我们与武汉化工原料厂协作,对4-氯-4′-羟基二苯砜钾盐真空熔融缩聚合成聚苯砜醚的途径进行过一些探索,得到了较好的结果。但是,在实践中发现,由于这一反应速度快,放出的热量大而集中,在真空中聚合热不易导出,随着单体用量

| Abstract: | The specific behaviour of some inorganic salts as diluents in melt-polyeondensa-tion of the potassium salt of 4-chloro-4'-hydroxy diphenyl sulfone under reduced pressure was studied. Alkali metal salts have little or no effect, but alkali earth metal and other metal salts depress the product molecular weight greatly. It was shown that sodium chloride can be used as solid diluent to give better temperature control in the polycondensation reaction. |
