PURPOSE: Provided is a method of preserving colloid-stabilized polymer emulsions against biodeteriogenic microbe attack and spoilage using selected cationic compounds. Also, provided is compositions containing colloid-stabilized polymer emulsions and cationic compounds that are resistant to spoilage by biodeteriogenic microbes. CONSTITUTION: The aqueous polymer emulsion composition resistant to biodeteriogenic microbe contamination comprises an aqueous polymer emulsion stabilized with a protective colloid and a cationic compound selected from the group consisting of a substituted guanidine salt, a substituted pyridinium salt, a tetrasubstituted ammonium salt, a polymeric cationic compound, and mixtures thereof, wherein the substituted guanidine salt and the substituted pyridinium salt are substituted with an alkyl, a cycloalkyl, or an aryl group containing 2 to 18 carbons and the tetrasubstituted ammonium salt is substituted with one or more of an alkyl, a cycloalkyl, and/or an aryl, said polymer emulsion containing little or no nonionic or anionic surfactants and little or no anionic substituents.
