Abstract:
1. A method of making a bioactive cationic polymer latex comprising initiating an emulsion polymerization of an aqueous composition comprising, at any time during the emulsion polymerization: a) at least one ethylenically unsaturated first monomer; b) at least one ethylenically unsaturated second monomer that is cationic or a precursor to a cation; c) at least one bioactive component; d) at least one free-radical initiator; e) optionally, at least one sterically bulky ethylenically unsaturated third monomer; f) optionally, at least one sterically bulky polymer; and g) optionally, at least one non nonionic surfactant.
