Abstract
Abstract An emulsifying agent for emulsion polymerization comprising at least one compound selected from the group consisting of (i) betaine esters of polyoxyalkylene alkyl ethers, (ii) betaine esters of polyoxyalkylene alkylphenyl ethers, (iii) betaine esters of polyoxyalkylene dialkylphenyl ethers, (iv) betaine esters of polyoxyalkylene phenyl ethers having two or more benzene nuclei, and (v) betaine esters of polyoxyalkylene polyol ethers. This emulsifying agent is suitable for use in the emulsion polymerization of polymer emulsions capable of forming a film having an excellent water resistance, transparency, and smoothness.
