Polymerization process for ionic monomers

摘要

The present invention describes a controlled polymerization process for (co)polymerization of radically polymerizable ionic monomers, comprising initiating the polymerization of free radically (co)polymerizable ionic monomers in the presence of a system initially comprising a transition metal complex, and an initiator comprising a radically transferable atom or group; and an excess of one or more uncomplexed ligands. It further describes a controlled polymerization process for the preparation of water soluble block copolymers comprising polymerizing radically (co)polymerizable monomers in the presence of a system initially comprising a water soluble macroinitiator, and a transition metal complex comprising one or more ligands.
