Vinyl acrylic copolymers and methods of making and use thereof

A carpet tile having a surface coated with an adhesive formulation, wherein the adhesive formulation comprises an aqueous dispersion comprising water and a copolymer derived from:

• vinyl acetate;
• an acrylate monomer having a glass transition temperature (Tg) of −30° C. or less;
• a carboxylic acid, a carboxylic acid anhydride, or a combination thereof;
• and
• an organosilane;
• in the presence of maltodextrin;
• wherein the adhesive formulation has a minimum viscosity of 5,000 Cp or more and does not fluctuate more than 1000 Cp over a 1 day period as measured by a #5 spindle at 20 RPM on a Brookfield viscometer at a solids content of 75-85%;
• and
• wherein the aqueous dispersion comprises a plurality of copolymer particles having a volume average particle size of from 80 nm to 500 nm.
