Patent ID: 7700703

Claim:
A polymeric additive for modifying tack, peel, shear, wetting, rheology, stability, plasticity, plasticizer compatibility or glass transition temperature of an aqueous emulsion polymer, wherein the polymeric additive comprises: an aqueous acrylic emulsion polymer comprising, as copolymerized units, 0.25% to 99.75% by weight, based on dry polymer weight, of one or more monoethylenically unsaturated nonionic C1-C10(meth)acrylic monomer, from 0.40% to 99.75% by weight, based on dry polymer weight of one or more ethylenically unsaturated surfactant monomers and from 0.25% to 2.5% by weight, based on dry polymer weight, of one or more monoethylenically unsaturated acid monomer; the aqueous emulsion polymer having a Tg of −100° C. to 100° C. and a weight average molecular weight between 1,000 and 40,000.
