Abstract
The present disclosure describes a two-step batch dispersion polymerization process for the preparation of substantially uniformed-sized functional (co)polymer particles. The first step of the process includes polymerizing at least one first radically (co)polymerizable monomer by a free radical polymerization process to form a (co)polymer in a stable colloidal dispersion and the second step includes polymerizing the at first radically (co)polymerizable monomer or an additional radically (co)polymerizable monomer in the stable colloidal dispersion by a living/controlled radical (co)polymerization process.
