ABSTRACT:
A method is provided for controlling polymer particle size in emulsion polymerization in which at least one emulsifier is added to a polymerization reaction mixture containing at least one ethylenically unsaturated monomer at a rate determined by the rate at which heat is evolved by free radical catalyzed polymerization of the monomer such that the total amount of emulsifier fed to the reaction mixture up to any one time is related to the total amount of heat evolved up to that time.
