Abstract: Waterborne vinyl acetate-acrylic, "vinyl acrylic" emulsion copolymers which can be used in architectural coatings and impart stain resistance to such coatings are provided. The vinyl acrylic emulsion copolymer particles in the emulsion may contain one or more particle size modes, each with a respective narrow particle size distribution. The vinyl acrylic emulsion copolymers contain as a comonomer an ethylenically unsaturated monomer and also contain a hydrolyzable silane comonomer. The hydrolyzable silane may be present as a comonomer in the vinyl acrylic copolymer and/or may be added to the vinyl acrylic emulsion copolymer emulsion in the form of a hydrolyzable silane that may have a reactive group that is capable of reacting with the vinyl acrylic copolymer.

Abstract: Multi-stage polymeric particles are prepared as a water-borne emulsion, including a first-formed lower Tg soft stage and a second-formed higher Tg hard stage. The polymeric particles include, in both stages: one or more free radical polymerizable ethylenically unsaturated monomers; 0 to 3 wt% of free radical polymerizable surfactant monomer; 0 to 4 wt% of free radical polymerizable monomer having a beta dicarbonyl functionality; 0 to 2 wt% of monomer selected from acrylamide, diacetone acrylamide, 2-hydroxyethyl (meth)acrylate, hydroxypropyl (meth)acrylates, and hydroxybutyl (meth)acrylates and mixtures thereof; 0-1.9 wt% of free radical polymerizable polyethylenically unsaturated monomers; 0.1 to 1.9% of free radical polymerizable monomer containing phosphorus acid or a salt thereof in the first stage, and 0.1 to 5 wt% of a free radical polymerizable monomer containing phosphorus acid or salt thereof in the second stage. Multi-stage polymeric-particle-based-resin is formulated into direct to metal coatings, having good block, corrosion and excellent humidity resistance.
