Abstract
This invention provides waterborne polymer compositions stabilized against gelling due to the addition of a poly(alkylenimine) by post addition of certain anionic surfactants. The waterborne polymer compositions of the invention are useful in a variety of coating formulations such as, for example, paints, inks, sealants, textile back coatings, adhesives and the like. Methods of making stable waterborne polymer compositions are also disclosed.
