Describes terminally ethylenically unsaturated poly(alkyleneoxy) surfactant compounds of the general formula, R--O--(R'O).sub.m --(EO).sub.n-1 --CH.sub.2 CH.sub.2 --X, wherein R is the ethylenically unsaturated hydrocarbon group, e.g., allyl, R' is the bivalent radical derived from butylene oxide, E is the bivalent ethylene radical, m and n are numbers of from 10 to 15 and 10 to 40 respectively, and X is chloride, tertiaryamino, sulfonate, sulfate, phosphate, isethionate and alkali metal salts of the anionic groups. These surfactant compounds may be used in emulsion polymerization of ethylenically unsaturated, e.g., vinyl, monomers.
描述了一种末端乙烯基不饱和聚(烷氧基)表面活性剂化合物,其一般式为 R--O--(R'O).sub.m --(EO).sub.n-1 --CH.sub.2 CH.sub.2 --X,其中 R 是乙烯基不饱和烃基,例如烯丙基,R' 来自丁二醇氧化物的双价基团,E 是双价乙烯基团,m 和 n 分别为10到15和10到40的数字,X 是氯化物、三级胺、磺酸盐、硫酸盐、磷酸盐、异硫酸盐和阴离子基团的碱金属盐。这些表面活性剂化合物可用于乙烯基不饱和单体的乳液聚合,例如乙烯基单体。
