Abstract
Described are anionic surfactants which are made by (1) reacting maleic acid, fumaric acid, itaconic acid or mixtures thereof with at least one selected epoxy-capped poly(oxyalkylated) alcohol in the presence of a peroxy-type free radical initiator to form a carboxylic acid group-containing addition product and (2) neutralizing said addition product with a sufficient amount of a neutralizing agent to convert at least a major proportion of said carboxylic acid groups to salt groups. These surfactants exhibit excellent surface activity as well as being highly soluble in caustic solutions.
