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.
