Abstract
A process is provided for the preparation of (co)polymer emulsions or suspensions from a full range of free radically (co)polymerizable monomers, wherein the (co)polymers exhibit the characteristics of "living" polymerization, including one or more of predictable molecular weights, narrow or controllable molecular weight distributions and a variety of polymer architectures, including the roles of surfactants, catalyst and ligands, several initiation methods, and methods for catalyst removal from the emulsions or suspensions made, and the (co)polymer emulsions and suspensions made thereby.
