Abstract:
An aqueous coating composition comprising an aqueous polymer formed by emulsion polymerization, said polymer having a glass transition temperature (Tg) from greater than 20Â° C. to 80Â° C., formed by the free radical polymerization of at least one ethylenically unsaturated nonionic acrylic monomer and 0-7.5%, by weight based on the total weight of said polymer, ethylenically unsaturated acid monomer in the presence of 0.01-1.0%, by weight based on the total weight of said polymer, t-alkyl hydroperoxide, t-alkyl peroxide, or t-alkyl perester wherein the t-alkyl group includes at least 5 Carbon atoms, and, optionally, at least one other oxidant.
