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.
Claims62
A polymer emulsion comprising:
- a combination of particles that include both VAE copolymers and (meth)acrylic polymers or copolymers, and optionally particles that include only (meth)acrylic polymers or copolymers,
- wherein the (meth)acrylic polymers or copolymers is prepared by polymerization and/or copolymerization of a (meth)acrylic monomer mixture.
A process for producing a polymer emulsion comprising:
- providing a vinyl acetate-ethylene copolymer dispersion as a seed;
- providing a monomer feed;
- providing an initiator;
- combining the vinyl acetate-ethylene copolymer dispersion, the monomer feed, and the initiator.
