摘　　要：合成了不同磺酸盐含量的三种不饱和聚酯,通过拟三元相图分析磺酸盐含量、苯乙烯、不同正构醇和水组成的体系对微乳区域的影响。研究结果表明,磺酸盐不饱和聚酯同苯乙烯互溶的前提下,磺酸盐含量越大,其微乳液增溶的水量越大;磺酸盐含量一定时,苯乙烯含量越小,其微乳液增溶的水量越大;正构醇质量分数为在2%～10%范围内,其微乳液增溶的水量最多;三种醇相比较,正丁醇体系的微乳区是W/O型向O/W型过渡的连续区域,正丙醇体系的O/W型微乳液区明显不同于正丁醇体系,正戊醇体系不能形成水包油型的微乳区。The unsaturated polyester resin with different contents of sulfosalt(mol%: 7.8,5.9 and (3.9)) was synthesized.The effect of alcohols (n-propanol,n-butanol and n-pantanol),sulfosalt unsaturated polyesters(SUP) and styrene on phase behaviour for the system of SUP /alcohols/styrene/water was studied.The results show that micro emulsion regions decrease as the increase of styrene at the constant of SUP/styrene ratio;The formation and characteristic of micro emulsion regions are affected markedly by the different alcohols and their contents,the oil in water (O/W) micro emulsion regions can not form as using n-pentanol cosurface;and microemulsion regions increase as the increase of sulfosalt contents of unsaturated polyester.
