Polymers stabilized by water-soluble, cationic, amino-functional polymer, and plastic film coated with same

摘要

A cationically stabilized emulsion polymer is disclosed which comprises a combination of at least one polymerizable monomer which is uncharged or positively charged in an aqueous solution having a pH between 1 and 8, polymerized in the presence of at least one water-soluble polymer having a number-average molecular weight greater than 5000 which comprises a moiety selected from the group consisting of primary amines, secondary amines, tertiary amines and quaternary ammonium salts. Coating compositions containing the cationically stabilized emulsion polymer and plastic films thus coated are also disclosed.
