  • Chalk adhesion polymer composition and method of preparation
    Patent number: 4722965
    Abstract: A chalk-adhesion polymer latex for exterior coatings especially suitable for blending with an acrylic formulation, such as vinyl acetate/ acrylic copolymers. The polymer is derived from a monomer precursor composition, including an acrylic moiety, such as an acrylate and a methacrylate, together with small amounts of a nitrogen-containing alkyl acrylate, an acrylamide and propylene glycol. The method of preparing the chalk adhesion polymer includes emulsification stages to accomplish the polymerization.
