Abstract:
A method of stabilizing an aqueous coating formulation, comprising a step of adding a polymer dispersion to the aqueous coating formulation, wherein said polymer dispersion comprises(i) an acrylate polymer prepared by polymerizing from about 30 to about 60% by weight of at least one C.sub.1 to C.sub.8 alkyl (meth)acrylate monomer, from about 30 to about 60% by weight of at least one vinylaromatic monomer, and from about 0.5 to about 10% by weight of (meth)acrylic acid, and(ii) a nonassociative rheology stabilizer comprising an acrylate copolymer prepared by polymerizing at least one C.sub.1 to C.sub.8 alkyl (meth)acrylate monomer and (meth)acrylic acid.
