PURPOSE: To prepare an emulsifier for aqueous emulsion polymerization of ethylene unsaturated monomer by using an allyl phenol sulfuric acid easter compound. n CONSTITUTION: An emulsifier for aqueous resin dispersion containing at least one of the compounds shown in the formula as a feature is provided in the following process. Alkyl phenol such as nonyl phenol or the like is used as raw material and allyl chloride is heat reacted in the presence of catalyst and vacuum distilled. Alkylene oxide is added to the prepared reactive composition, and sulfation is carried out by sulfating agents such as sulfuric acid, sulfamine and the like, being neutralized, if necessary. Said emulsifier is used for aquatic emulsion polymerization of ethylene unsaturated monomer. 0.1W20wt% of emulsifier is preferably used against the total monomer. n COPYRIGHT: (C)1987,JPO&Japio |
