    摘要: The present invention relates to a preparation method of a metallocene catalyst. More particularly, the present invention relates to a preparation method of a supported hybrid metallocene catalyst, including the steps of treating a support having a water content of 4 to 7% by weight with trialkyl aluminum at a predetermined temperature; supporting alkyl aluminoxane on the support; and supporting a metallocene compound on the alkyl aluminoxane-supported support. According to the present invention, it is possible to prepare a supported hybrid metallocene catalyst which shows a high activity in the polymerization of olefins and enables the preparation of polyolefins having a high bulk density, by a simple process.

    摘要: 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.
