Abstract
This invention is directed to a method of preserving polymer emulsions against biodeteriogenic microbe attack and spoilage by combining with the polymer emulsions selected cationic compounds and an ethylenediamine acid compound. The polymer emulsions contain surfactants and/or anionic constituents. It is also directed to polymer emulsion compositions, that are resistant to spoilage by biodeteriogenic microbes, containing surfactants and/or anionic constituents, an ethylenediamine acid compound, and cationic compounds.
