PROCESSES FOR CHEMICALLY-MODIFYING THE SURFACE OF EMULSION POLYMER PARTICLES

摘要

Processes for chemically-modifying the surface of an emulsion polymer particle are provided which include providing an aqueous emulsion polymer, a monomer at a level of at least 0.5% by weight based on the weight of the emulsion polymer and a surface-modifying chemical capable of bonding with th e monomer, under conditions where there is no substantial polymerization of th e monomer, and then reducing the level of the monomer by at least 50%.
