Abstract
Novel salts of alkenylsuccinic monoesters represented by the following formulas (I) or (II): ##STR1## in which R.sub.1 represents a hydrocarbon group, R.sub.2 represents a hydrogen atom or a methyl group, A represents an alkylene group having from 2 to 4 carbon atoms, B represents a carbonyl group or a methylene group, M is a monovalent or divalent cation. The monoesters can be emulsion-polymerized under optimum conditions while varying the hydrophilic and oleophilic balance depending on the type of monomer because they have hydrophobic hydrocarbon groups and oleophilic carboxylate groups and ether bonds of polyalkyleneoxy groups. The compounds according to the invention are an excellent reactive surface active agent, and also useful as an improver or modifier for polymer because they can impart hydrophilicity to hydrophobic resins when they are used in larger amounts as in the case of reactive surface active agents employed for ordinary.
