<p>A method for providing a caulk, sealant, elastomeric coating, pressure sensitive adhesive, or fabric treatment including: forming an aqueous composition including an aqueous acrylic emulsion polymer, the polymer including, as copolymerized units, 70 to 99.7% by weight, based on dry polymer weight, monoethylenically unsaturated nonionic (meth)acrylic monomer and from 0.3 to 10% by weight, based on dry polymer weight, monoethylenically unsaturated acid monomer, wherein the Tg of the emulsion polymer is from -90 DEG C to lower than -20 DEG C, and wherein at least 40% by weight, based on dry polymer weight, of the polymer is formed by redox polymerization in the presence of 0.0005 to 0.05 moles chain transfer agent per kg dry polymer weight; applying the aqueous composition to a substrate; and drying, or allowing to dry, the applied aqueous composition.</p> |
