摘　　要：通过热失重法并结合元素分析,研究了3种不同致孔剂的阳离子交换树脂功能基团的热分解。结果表明,25~400℃范围内,3种树脂的热分解分为2个阶段,其中一阶失重是功能基团上结合水脱去的过程,二阶失重是聚苯乙烯骨架未发生分解,功能基团发生分解的过程。本文的研究对于离子交换树脂行业有一定参考意义。The thermal decomposition of functional groups in 3 kinds of cation exchange resins prepared with different pore forming agents was studied by thermogravimetry and elemental analysis. The results show that, within the range of 25~400 ℃, thermal decomposition of 3 kinds of resins can be divided into 2 stages, first-order weightlessness is the removal process of bound water on functional groups, second-order weightlessness is the decomposition process of functional groups. This study has certain reference significance for the ion exchange resin industry.
