| 摘 要： | 高分子树脂水基化微粒化就是使高分子树脂以微粒形式分散于水中，高分子乳液、悬浮液都属于此范畴．因其不含有机溶剂，且具有无环境污染及不易失火等优点，放这方面的研究正成为高分子技术的一个研究热点．通常的乳液聚合或悬浮聚合方法是从小分子单体到聚合物水基化体系的化学反应过程，一般只适于制备加聚物的水基化体系，而不适用于制备维聚物的水基化体系．本文提出的相反转技术是一种有效的制备高分子水基化体系的方法，它能将几乎所有的高分子树脂通过物理的乳化方法制成相应的水基化体系[1，2]，大大拓宽了其制备范围．相反转[3。4]…

| Abstract: | The waterborne particles of bisphenol A epoxy resin were prepared by the phaseinversion technique, and the effects of the concentration of the synthetic polymeric emulslfleron the particles size and structure were discussed. At lower concentration of the emulsifier,the bigger molecular sieves alike particles were obtained, on the contrary, the smallerparticles with some aggregation were prepared at higher concentration of the emulslfler. Theformation mechanism of different particle sizes and structure at different concentrations of theemulsifier was proposed. presides, the probable model of the aggregation was also brieflypresented. |
