  • Patent number: 8916664
    Abstract: An ethylene oligomerization catalyst that oligmerizes ethylene to a series of ?-olefins and that has a Schulz-Flory constant of about 0.75 to 0.995 produces a stream of ?-olefins. This stream is then added to a vessel containing ethylene and a copolymerization catalyst that copolymerizes ethylene and ?-olefins. The resulting branched polyethylene often has good processing properties. The good processing is presumably due to the presence of “long chain branching”. Such polymers are useful for films and other packaging materials, and for molding resins for molding parts such as industrial, automotive or electrical parts.

  • Patent number: 8133835
    Abstract: Provided are a molecular weight controllable, high 1,4-trans polybutadiene catalyst system, and more particularly, a four-component catalyst for preparing 1,4-trans polybutadiene with high yield, the catalyst comprising a cobalt compound, an organoaluminum compound, a phenol-based compound, and a phosphorus-based compound used to prepare 1,4-trans polybutadiene by polymerizing butadiene or a butadiene derivative, and capable of controlling the molecular weight of 1,4-trans polybutadiene by regulating the amount of the phosphorus-based compound. In particular, 1,4-trans polybutadiene may be efficiently applied to tires, belts, or the like since it has excellent tensile strength, tear strength, and cut & chip properties with increasing processability.

  • Patent number: 8017706
    Abstract: The present invention relates to a novel iron complex having a cyclic amine compound as a ligand and a method for producing polymers by polymerizing a radical polymerizable monomer in the presence of the iron complex and a radical generator. The problem for the present invention is providing a method capable of producing a polymer or block copolymer having a chemically convertible functional group at the end from a radical polymerizable monomer and providing a method for recovering the iron complex in a solvent with a high recovery rate after the polymerization reaction. This problem is solved by providing a novel iron complex, a method for producing a polymer in the presence of a radical polymerization initiator that uses the iron complex as a polymerization catalyst and a method for simply and easily recovering the iron complex.

  • Patent number: 8003740
    Abstract: Method of preparing olefin polymers, which comprises the polymerization of at least one ?-olefin in the presence of a hybrid catalyst to produce a polymer comprising at least a higher molecular weight polymer component and a lower molecular weight polymer component in the presence of water in an amount of from 2 to 100 mol ppm and/or carbon dioxide in an amount of from 2 to 100 mol ppm, in each case based on the total reaction mixture, in order to alter the ratio of the higher molecular weight polymer component to the lower molecular weight polymer component. This enables the ratio of the higher molecular weight component to the lower molecular weight component to be controlled selectively.
