Latest Patents
YoungGyu Han holds a patent for a method titled "Precise control of molecular weight and chain shape control in carbon dioxide/epoxide alternating copolymerization and preparation of low molecular weight poly(alkylene carbonate)." This invention focuses on a technique for preparing poly(alkylene carbonate) with precisely controlled molecular weight and polymer chain structure. The method involves the addition of a chain transfer agent containing an alcohol or carboxylic acid functional group during the copolymerization of an epoxide compound and carbon dioxide. The catalyst used is a trivalent metal complex compound synthesized from a quaternary ammonium salt-containing Salen type ligand. This innovation allows for the preparation of both star-shaped and linear chain polymer compounds. The resulting low-molecular-weight poly(alkylene carbonate) features an —OH terminal group, making it suitable for use as a coating agent and in mixtures with isocyanate compounds for polyurethane production.
