ABSTRACT:
The average particle size of latices of polymers prepared by aqueous emulsion polymerization of ethylenically unsaturated and/or diolefinic monomers is increased markedly by admixture therewith of polyethoxylated surfactants having an HLB Value of 16-19.5 which are based on either long chain alkyl amines and/or esters of aliphatic polyols and fatty acids.
