Abstract:
An emulsion polymer formed by the free radical polymerization of at least one first ethylenically unsaturated monomer until at least 95% of said first monomer by weight has been converted to a first emulsion polymer and subsequent treatment of said first emulsion polymer with 0.01-6%, by weight, based on the weight of said first emulsion polymer, of a colloidal stabilizer, 1-10%, by weight, based on the weight of said first emulsion polymer, of at least one second ethylenically unsaturated monomer, and 0.05-0.35%, by weight, based on the weight of said first emulsion polymer, of a redox system at 20-85Â° C. until at least 90% of the sum the residual monomer of said first emulsion polymer and said second monomer has been converted to polymer.
