Abstract: Three chlorostyrene strongly acidic cation exchange resins were prepared from o-, m-, p-chorostyrene and divinylbenzene. The thermal stability of o-chlorostyrene strongly acidic cation exchange resin was the highest. In water at 170℃ the degradation of the prepared resin was less than 14.0% in 100 hours, and degradation rate was 0.0028%/h. In the transalkylation of dinonanylphenol with phenol by using the prepared resin as catalyst, the conversion of dinonanylphenol was more than 99%, and the resin had good stability in this reaction system.

摘要： 用邻氯苯乙烯、间氯苯乙烯、对氯苯乙烯与二乙烯基苯合成3种氯代苯乙烯强酸性阳离子交换树脂，考察它们的热稳定性，结果表明：以邻氯苯乙烯强酸性阳离子交换树脂的热稳定性能最好，在170 ℃的水介质中，磺酸基100 h热降解率小于14.0％，降解速率为0.002 8％/h。用作二壬基酚和苯酚烷基化转移反应的催化剂，二壬基酚的转化率达99％以上，树脂在反应体系中稳定.
