POLYOLEFIN-BASED COPOLYMER AND METHOD FOR PREPARATION OF THE SAME

摘要

The present invention relates to a polyolefin-based copolymer which has a wide molecular weight distribution and excellent flowability, and a production method of the same. More specifically, the polyolefin-based copolymer is obtained by the production method which comprises a step of polymerizing more than one kind of olefin monomers under the presence of a catalyst composition which contains a specific transition metal compound with at least one low class alkyl substitution group in a ring structure as a catalyst.
