Latest Patents

One of Liu's latest patents is titled "Hydrogenation of diene-based polymer latex in the presence of an in situ synthesized catalyst." This technique improves the hydrogenation reaction of diene-based polymers present in aqueous suspension. The process involves in-situ synthesizing the catalyst in the presence of a specific aliphatic alcohol. This innovation allows for the selective hydrogenation of carbon-carbon double bonds in diene-based polymers with a high degree of hydrogenation and short reaction times. The improved process eliminates the complicated catalyst synthesis operations that were previously necessary.

Another significant patent is "Tandem metathesis and hydrogenation of diene-based polymers in latex." This invention provides a novel process for subjecting a diene-based polymer to a metathesis reaction in a first step, followed by a selective hydrogenation of the carbon-carbon double bonds in a second step. This process utilizes a ruthenium or osmium-based complex catalyst, with the diene-based polymer present in latex form, meaning as a suspension of diene-based polymer particles in an aqueous medium.
