Title:
METHOD OF POLYMERIZING OLEFIN, NOVEL POLYETYLENE AND FILM AND ARTICLE MANUFACTURED FROM THE SAME
Document Type and Number:
Japanese Patent JP2011026612
Kind Code:
A
Abstract:
To provide a polymerizing method for an olefin homopolymer or interpolymer having a narrower molecular weight distribution.
The method of polymerizing olefin includes a process of bringing at least one kind of olefin into contact with a Ziegler-Natta type catalyst in the presence of a specified compound capable of producing a polymerization product having a relatively narrow molecular weight distribution to produce a polyolefin having a narrow molecular weight distribution.
