A novel method combining a conventional free-radical solution polymerization with a chemical saponification was used to synthesize a, cu-dicarboxyl terminated oligo s with molecular weight below 1500. Here, cn-carboxyl terminated oligo s were firstly synthesized by the free-radical polymerization in THF, where 4,4'-azobis(4-cyanovaleric acid) was used as initiator, thioglycolic acid as chain transfer agent, then CTBMA were transformed into di-CTBMA via saponifying CTBMA in dioxane/H_2O/KOH solution.

利用传统自由基聚合法，在四氢呋喃溶液中自由基引发聚合甲基丙烯酸丁酯单体而得到w-羧基-甲基丙烯酸丁酯低聚物(分子量在1500左右)；利用CTBMA 末端酯基的反应特性，在二氧六环／水／KOH混合溶液中皂化CTBMA，使之转化为a ，w-羧基甲基丙烯酸丁酯低聚物；研究了溶剂的类别、反应时间等反应条件对皂化产物结构的影响；利用MALDI-TOF-MS及LSIMS对皂化各阶段产物进行了分析监测。
