Patent ID: 8410232

Claim:
A method of polymerization comprising: supplying a monomer having one or more of the following structures: wherein R 1 and R 2 are selected from a hydrogen, a C 1-18 alkyl group, or an aromatic group, or a cyclic alkyl group, or combinations thereof and wherein R 3 is selected from an alkylene group, aromatic group, cyclic alkyl group, heterocyclic group, or combinations thereof; supplying seed particles comprising polymer particles dispersed in an aqueous medium containing emulsifying agents and adding said monomer to said aqueous medium wherein said seed particles absorb said monomer; and polymerizing said monomer to a polymer having a particle size wherein said seed particles control said particle size of said polymerized monomer and wherein said polymer includes 50.0 weight percent or higher of an ester of itaconic acid.
