Abstract: Carpet binder compositions comprising a mineral filler and a copolymer produced by emulsion polymerization and derived from monomers comprising a vinyl aromatic monomer, a 1,3-diene monomer, and an additional monomer selected from a copolymerizable surfactant, a (meth)acrylate monomer, a carboxylic acid monomer, or a combination thereof are disclosed. The carpet binder compositions can be formulated with a non-polymerizable surfactant such as an aryl phosphate surfactant. The compositions exhibit superior wet and dry delamination strengths as well as suitable froth viscosities. As a result, such carpet binder compositions can be made at higher filler loadings.

Abstract: 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.
