ABSTRACT:
Aqueous coating compositions comprising latices containing a copolymer of vinyl acetate in the range of about 95-99.9% by weight and maleic anhydride in the range of about 0.1-5% by weight have been found to have improved starch binder compatibility. Vinyl acetate and maleic anhydride are polymerized in an aqueous medium in the presence of a free radical initiator and a surfactant which prevents the vinyl acetate-maleic anhydride copolymer from dissolving in the aqueous medium. The resulting latex coating compositions have a high solids content (greater than about 50% by weight) and a copolymer particle size of under 0.5 microns in addition to the excellent starch compatibility.
