摘要

通过聚合 1,1,3,3-四甲基二氢二硅氧烷、D4、聚氧乙烯烯丙基和氯乙酸钠，合成了一系列羧基改性聚醚嵌段硅氧烷（CPES）表面活性剂。红外光谱和 1H-NMR 对表面活性剂的结构进行了表征。此外，还研究了合成产品的表面张力、润湿性能、泡沫性能、乳化性能和清洁性能。结果表明，这些化合物具有很高的表面活性和良好的发泡稳定性。润湿性能一般，但提高温度可改善产品的润湿能力。此外，CPES 表面活性剂还具有良好的乳化和清洁能力。

Synthesis and properties of carboxyl-modified polyether block silicone surfactants

A series of carboxyl-modified polyether block silicone (CPES) surfactants were synthesized by the polymerization of 1,1,3,3-tetramethyldihydrodisiloxane, D4, allyl polyoxyethylene and sodium chloroacetate. The structures of the surfactants were characterized by IR and ¹H-NMR. Furthermore, the surface tension, wetting properties, foam properties, emulsifying properties and cleansing properties of the synthesized products were investigated. The results show that these compounds have high surface activity and good foaming stability. The wetting properties are general, but increasing temperature can improve the wetting ability of the product. Besides, CPES surfactants exhibit good emulsifying and cleaning ability.

期刊介绍： "Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad. "Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
