摘要: 以乙酰磺酸为磺为磺化剂制备了磺化度为3~17mol%的磺化聚苯醚(SPPO),并中和成盐,在一定的温度和搅拌速度下,加水将SPPO离聚体溶液乳化成水包同的稳定水基微乳液。用光散射法及航向电镜法(TEM)测定了SPPO离聚体水基微乳液的粒径及粒径分布,研究了磺化度、溶剂的极性、因含量等因素对微乳液粒径及稳定性的影响。Abstract: Sulfonated poly(phenylene oxide)(SPPO) ionomers in different mixing solvents were emulsified by water to form a series of waterborne microemulsions.
