摘要
本文通过改变单体、乳化剂的配比等合成了不同的聚丙烯酸树脂乳液,同时对聚合物乳液进行了测试和分析,通过电导滴定法对乳液各相中羧基的分布进行了研究。结果表明:随着亲水性单体的增加,分布在各相中的羧基含量随之增加,乳液和聚合物的稳定性也有所提高。
In this paper,different polyacrylic acid resin emulsion was synthesized by changing the ratio of monomers and emulsifier. Polymer emulsion were tested and analyzed. Distribution of carboxyl groups in each phase emulsion were studied by conductometric titration. The results showed that with the increase of hydrophilic monomer,in each phase the distribution of the carboxyl content is also increased,It also improves the stability of the emulsion and the polymer.
