Abstract
The present invention relates to the use of Styrenated Phenol Ethoxylates as surfactants in emulsion polymerization. The present invention further relates to the use of both anionic and nonionic Styrenated Phenol Ethoxylates in emulsion polymerization. Latexes with small average particle and narrow particle size distributions are obtained. Prepared latexes also have low coagulum levels and exhibit excellent mechanical and chemical stability.
