用引发聚合方法合成了ＡＭＰＳ／ ＡＭ／ ＡＭＣ１４Ｓ 三元共聚物。研究结果表明，在单体总浓度１０ ％ —１５ ％ ，ＡＭＣ１４Ｓ浓度０ ．１５ ％ ，ｐＨ值为中性时，在３０—４０℃反应８ ｈ 可以得到转化率９７％ 、特性粘数１０ —１７ ｄＬ／ｇ 的共聚物。通过红外光谱研究了共聚物的分子结构，并通过差热分析研究了共聚物的耐热性。
The AMPS / AM / AMC14S terpolymer was synthesized by means of initiating polymerization. The results show that the total monomer concentration of 10% -15%, AMC14S concentration of 0. 15%. When the pH value is neutral, the reaction is carried out at 30-40 ℃ for 8 h to obtain a copolymer with 97% conversion and intrinsic viscosity of 10-17 dL / g. The molecular structure of the copolymer was studied by infrared spectroscopy, and the heat resistance of the copolymer was studied by differential thermal analysis.
