Latest Patents

Paik holds a patent titled "Catalytic processes for the controlled polymerization of free radically (co)polymerizable monomers and functional polymeric systems prepared thereby." This invention incorporates improvements in processes for the controlled polymerization of free radically (co)polymerizable monomers, which are mediated by a transition metal complex engaging in redox reactions. These reactions involve the transfer of a radically transferable atom or group between an initiator or dormant polymer and the growing active polymer chain ends.

Two significant enhancements within the patent relate to the selection of counterion in the transition metal complex. One enhancement allows the transition metal to remain close to a solid support through interactions with a counterion directly attached to the support, improving catalyst utilization, including recovery and recycling. Another enhancement, particularly effective for specific monomers, utilizes salt containing a soluble organic counterion, which optimizes the functionality of the transition metal-based catalyst. These advancements aid in preparing an extensive range of novel polymeric materials and innovative processes for creating functional polymers, including a unique catalytic Atom Transfer Coupling Reaction.
