Aqueous polymer formulation

Abstract

Provided is a composition comprising an aqueous medium, and further comprising, dispersed in the aqueous medium: (a) particles (a) that comprise a maleated polyolefin (a), and (b) particles (b) that comprise an acrylic polymer (b), wherein the acrylic polymer (b) comprises, by weight based on the solid weight of the acrylic polymer (b): (i) 0.1% to 10% polymerized units of hydroxyl functional acrylic monomer, (ii) 1% to 20% polymerized units of carboxyl functional monomer, and (iii) 70% to 98.9% polymerized units of one or more additional monomer (iii) selected from the group consisting of acrylic monomers, styrenic monomers, and mixtures thereof, wherein the maleated polyolefin (a) is present in an amount of 1% to 19% by weight based on the sum of the solid weights of maleated polyolefin (a) and acrylic polymer (b). Also provided is a method of binding fibers using the composition.
