Claim 0:
1. A method comprising:
a) dissolving a polymerizable benzophenone monomer in a reactive monomer composition to form a pre-emulsion, the polymerizable benzophenone monomer formed by reacting a diphenyl ketone having functional groups and a polymerizable component having one or more acrylate or vinyl moieties; and
b) emulsifying the pre-emulsion by combining the pre-emulsion with a radical initiator in a reactor to form a reaction mixture that polymerizes to form an emulsion polymer, wherein the polymerizable benzophenone monomer is described by structure 2:, , wherein:
m is 0, 1, 2, 3, 4, or 5;
n is 0, 1, 2, 3, or 4;
R1, R2 are each independently C1-10 alkyl, C6-14 aryl, C6-15 heteroaryl, —OH, —NH2, —R3—OH, —R3—NH2, epoxy group, carbonyl group, vinyl group, or acylate group;
R3 is a C1-10 alkenylene group; and
R4 is C1-10 alkyl.
