  • Patent number: 8232357
    Abstract: The present invention relates to a catalytic composition for producing a 1-alkene-acrylate copolymer that includes a metal nano catalyst, and a method for producing a 1-alkene-acrylate copolymer. In the catalytic composition for producing a 1-alkene-acrylate copolymer, since the content of the polar comonomer is high, it may be used to produce the 1-alkene-acrylate copolymer that has no crystallinity and is capable of being used as an optical material. The method for producing the 1-alkene-acrylate copolymer may be produced by using a simple process of a mild polymerization condition without a polymerization condition of high temperature and high pressure, and it is easy to control physical properties.

  • Patent number: 7915360
    Abstract: The present invention provides a new supported catalyst for olefin polymerization prepared by reacting a novel transition metal compound on a cocatalyst-supported support, in which the transition metal compound is coordinated with a monocyclopentadienyl ligand to which an amido-quinoline group is introduced, a method for preparing the same, and a method for preparing a polyolefin using the same. The transition metal catalyst compound used in the present invention is configured such that an amido group is linked in a cyclic form via a phenylene bridge. Thus, a pentagon ring structure of the transition metal compound is stably maintained, so that monomers easily approach the transition metal compound and the reactivity is also high.
