Abstract
A process for preparing a (meth)acrylate comprising preparing an aqueous phase by combining water, one or more stabilizing agents, and one or more surfactants; preparing an oil phase by combining one or more free radical initiators, one or more monomers capable of undergoing radical polymerization, one or more crosslinking and/or graft-linking monomers, and stearyl methacrylate and/or lauryl methacrylate, wherein the free radical initiator is capable of partitioning preferentially into the oil phase; combining the aqueous and oil phases and mixing to form a suspension having oil droplets ranging in size from 1 to 10 microns; raising the temperature of the suspension to effect an initial polymerization forming a core polymer is provided.
