Abstract
This invention provides stable waterborne polymer compositions, which are stabilized against gelling, comprising a stable waterborne polymer composition having a Tg of greater than about 0° C. and comprising an acetoacetoxy-type functional polymer, a poly(alkylenimine), and a nonionic surfactant having a hydrophilic-lipophilic balance (HLB) of at least about 17.5. The waterborne polymer compositions of the invention are particularly useful in a variety of adhesive formulations such as pressure sensitive adhesives, laminating adhesives, and the like. Methods of making stable waterborne polymer compositions are also disclosed.
