Abstract
Methods of producing hybrid polymer emulsions by incorporating a vinyl acetate-ethylene copolymer dispersion as the seed for subsequent polymerization of an acrylic and/or methacrylic monomer mixture are described. In certain embodiments, new particle formation is observed. Also described are the resulting polymeric products. And hybrid polymer emulsions formed from the methods with pressure sensitive adhesion performance are also described.
