  • Patent number: 10723837
    Abstract: Provided is a method of preparing poly(alkylene carbonate) using a molecular weight regulator in a process of preparing a copolymer of carbon dioxide/epoxide using a novel complex synthesized from salen-type ligand including a quaternary ammonium salt as a catalyst. According to the present invention, even though the molecular weight regulator is used, an activity of the catalyst may be stably maintained, whereby the low molecular weight of poly(alkylene carbonate) having a desirable level may be effectively provided. In addition, it is expected that since the novel complex as the catalyst of the present invention has a simple structure as compared to the existing copolymerization catalyst, due to the economical preparation cost thereof, the novel complex may be effectively applied to a large-scale commercial process.

  • Patent number: 9062155
    Abstract: The present invention relates to a method for producing an organometallic catalyst and an organometallic catalyst when produced by the method. The method comprises the steps of combining a polycarboxylic acid or anhydride and a metal-oxide, metal-hydroxide or metal-salt with a solvent at a temperature and pressure at which the solvent exists as a supercritical or near-critical fluid. The polycarboxylic acid or anhydride is reacted with the metal-oxide, metal-hydroxide or metal-salt for sufficient time and under sufficient temperature and pressure to produce the organometallic catalyst. The present invention also relates to a process for making a poly(alkylene carbonate) in the presence of a catalytic amount of the organometallic catalyst produced by the method.

  • Patent number: 9023979
    Abstract: This invention relates to a method of preparing poly(alkylene carbonate) that has a molecular weight and polymer chain structure precisely controlled by adding a chain transfer agent composed of a compound having an alcohol or carboxylic acid functional group upon alternating copolymerization of an epoxide compound and carbon dioxide using a catalyst composed of a trivalent metal complex compound synthesized from a quaternary ammonium salt-containing Salen type ligand, and to a polymer compound prepared thereby. According to this invention, the polymer compound having a star-shaped chain as well as the polymer having a linear chain can be prepared. The low-molecular-weight poly(alkylene carbonate) has an —OH terminal group and can be used alone as a coating agent, etc., and also in mixtures with an isocyanate compound and thus can be easily utilized to prepare polyurethane.
