Described herein are compositions comprising a vinyl acrylic copolymer derived in the presence of maltodextrin. In some examples, the compositions comprise a copolymer derived from: vinyl acetate; an acrylate monomer having a 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. The copolymer can be provided as an aqueous dispersion. In some examples, the aqueous dispersion can have an overall solids content of from 40% to 75%. Also disclosed herein are carpet tiles having a surface coated with the adhesive formulations disclosed herein. In some examples, the carpet tile with the adhesive formulation applied thereto can pass the British spill test. Also disclosed herein are methods of making the compositions disclosed herein.
