The present invention relates to an ethylene-alpha olefin copolymer comprising long chain branches (LCB), while having a narrow molecular weight distribution. The ethylene-alpha olefin copolymer can be prepared by a continuous solution polymerization process using an activated catalyst composition containing a Group 4 transition metal compound having a monocyclopentadienyl ligand, to which a quinoline amino group is introduced.

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.

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. Accordingly, if the supported catalyst for olefin polymerization prepared according to the present invention is applied to the copolymerization of ethylene and monomers having large steric hindrance in a slurry or a gas phase process, a linear, a linear, high molecular weight polyolefin having a very low density of 0.900 to 0.970 g/cc or less can be obtained.
