摘要： Polymeric latices formed by free radical initiated polymerization of a polymerizable alpha, beta-ethylenically unsaturated monomer component which contains from 0.1 to less than 30 percent by weight of an epoxy group-containing alpha, beta-ethylenically unsaturated monomer in aqueous medium and in the presence of a salt of an acid group-containing polymer are disclosed. The resultant polymeric latices have higher molecular weights than polymeric latices prepared without the epoxy group-containing alpha, beta-ethylenically unsaturated monomer. The polymeric latices are useful as resinous binders in coating compositions where they provide for excellent adhesion and flexibility in the coating.
