Patent ID: 8822585

Claim:
An aqueous dispersion of polymeric particles, the particles comprising: 80% to 99.9% by weight, based on a weight of the polymeric particles, of at least one ethylenically unsaturated monomer; and 0.1% to 20% by weight, based on the weight of the polymeric particles, of a copolymerized macromer, having a number average molecular weight of between 1,000 and 50,000 and a cloud point of a 1% by weight solution in water of between 27° C. to 85° C.; wherein the polymeric particles have an average particle diameter of 20 to 1000 nanometers, and wherein the copolymerized macromer is formed by polymerization of at least one monoethylenically unsaturated monomer in the presence of at least one chain transfer agent, where the chain transfer agent contains a reactive functionality X, to make a premacromer, and the premacromer is post reacted with an ethylenically unsaturated monomer which contains a complementary reactive functionality Y, such that X and Y will react to form a covalent bond.
