摘　　要：通过在水中加热不同结构的磺化苯乙烯－二乙烯苯共聚物，研究了常见凝胶型和大孔型强酸阳离子交换树脂在１７０℃和１９０℃水介质中的热稳定性。结果表明其热稳定性顺序分别为：Ｓ—１００＞ＳＫ—１Ｂ＞００１×７＞Ｃ—２０＞ＨＣＲ—Ｓ（Ｅ）；Ｄ６１＞Ｄ００１ＣＣ＞Ｄ７２＞ＡｍｂｅｒｌｙｓｔＡ—１５，并在此基础上合成了具有较高热稳定性的新型大孔树脂。The thermal stabilities of several gel and macroporous strongly acidic cation-exchange resins in water were studied at temperatures of 170℃ and 190℃ , respectively. The plotes of the percentage of loss of ion-echange capacity of the resin versus time show that the thermal stabilities of the gel resins vary in the order of S - 100>SK - 1B> 001 × 7>C - 20>HCR - S (E), whereas those of the macroporous resins vary in the order of D61 >D001CC>D72>18> A-15. 18 is a newly synlhesized resin in our lak.
