摘要
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.
