| 摘 要： | 利用功能性单体甲基丙烯酸(MAA)、甲基丙烯酸十八烷基酯(SMA)和聚乙二醇甲基丙烯酸酯(PEG-MA)通过自由基共聚,合成了两亲性共聚物Poly(MAA-SMA-PEGMA)。研究了其结构、临界胶束浓度(CMC)和表面张力,探讨了由共聚物与低分子表面活性剂组成的复配体系。结果表明高低分子表面活性剂复配体系在质量比为5∶5后,体系的表面张力和临界胶束浓度都有所降低,接近于低分子表面活性剂。

| Abstract: | The amphiphilic copolymer poly(MAA-SMA-PEGMA)had been synthesized by the free-radical copolymerization of methacrylic acid(MAA),stearyl acryate(SMA) and poly(ethylene glycol) acrylate(PEGMA).The critical micelle concen-tration(CMC) and surface tension of the copolymer were investigat-ed.In addition,the mixture of the polymer surfactant and the small molecular surfactant was discussed.The results show that the surface tension and CMC of mixture decreased dramatically at molar ratio of 5:5. |
