PURPOSE:To enhance the emulsifying effect of the title emulsifier on an adhesive, a coating agent, etc., by preparing the emulsifier for an aq. resin dispersant with a mixture of the two kinds of compds. being the emulsion polymerization products and expressed by the specified general formulas. CONSTITUTION:Nonylphenol, etc., are used as the raw material, the material is heated in the presence of an allyl glycidyl ether catalyst, and an alkylene oxide is added to the reaction product. The product is allowed to react with maleic anhydride, neutralized with a basic substance, and sulfated by a sulfating agent such as sodium hydrogen sulfite to obtain the emulsifier consisting of a mixture of the compds. expressed by formulas I and II [R stands for 8-30C alkyl, alkenyl, alkylaryl, aralylaryl groups, A is 2-4C alkylene. (n) is 0-100 integer, (m) is 1-200 integer, and M1 and M2 show an alkali metal atom, NH4, etc.}.
