The invention discloses a polymer surfactant for emulsified oil. The polymer surfactant is obtained by copolymerizing allyl polyethenoxy ether, unsaturated anhydride and alkyl acrylate. The preparation method of the polymer surfactant includes the steps that in an acetone solvent, allyl polyethenoxy ether, unsaturated anhydride and alkyl acrylate are subjected to radical polymerization in different molar ratios as comonomers to obtain the polymer surfactant. The polymer surfactant prepared through the preparation method can be used for emulsifying ester oil serving as lubricating oil. The surface tension of the prepared polymer surfactant ranges from 45 mN/m to 52 mN/m. 本发明公开种乳化油用高分子表面活性剂，由烯丙基聚氧乙烯醚，不饱和酸酐，丙烯酸烷基酯共聚得到；其制备方法为：在丙酮溶剂中，以烯丙基聚氧乙烯醚，不饱和酸酐，丙烯酸烷基酯为共聚单体以不同摩尔比通过自由基聚合反应得到种高分子表面活性剂。本制备方法制备的高分子表面活性剂可用作乳化酯类油用作润滑油。本发明所制备的高分子表面活性剂的表面张力范围为45mN/m~52mN/m。
