Abstract

Methods for preparing copolymeric emulsions from at least one water soluble monomer and at least one water insoluble monomer are disclosed herein. In some embodiments, one or more surfactants and stabilizers may be used. In some embodiments, the monomers used in the process include, by total monomer weight, at least 50% water soluble monomers and at least 10% water insoluble monomers. Copolymer emulsions formed from the reaction product of at least one water soluble monomer and at least one water insoluble monomer are also disclosed along with articles coated with such emulsions and coating formulations made from such emulsions as well as methods for the manufacture and coating of such articles.
