Latest Patents

Jian Qiu's latest patents include groundbreaking advancements in catalytic processes for the controlled polymerization of free radically (co)polymerizable monomers. One of his patents details improvements in processes mediated by a transition metal complex participating in a redox reaction. This process involves the transfer of a radically transferable atom or group to and from an initiator or dormant polymer, enhancing the efficiency of the growing active polymer chain ends. Notably, two improvements focus on the choice of counterion in the transition metal complex. One improvement allows the transition metal to be closely associated with a solid support through interaction with a counterion directly attached to the support, leading to better catalyst utilization, recovery, and recycling. The second improvement introduces the use of a salt containing a soluble organic counterion, which is particularly suitable for controlled polymerization of certain monomers with a broader range of transition metals. These advancements have facilitated the preparation of novel polymeric materials and innovative processes for functional polymers, including a unique catalytic Atom Transfer Coupling Reaction.
