Title:
METHOD OF CONTROLLING MOLECULAR WEIGHT DISTRIBUTION IN ETHYLENE/α-OLEFIN COMPOSITION
Document Type and Number:
Japanese Patent JP2014088566
Kind Code:
A
Abstract:

To provide a method of producing a polymer having a composition and a controlled molecular weight distribution.

In making an ethylene/α-olefin interpolymer composition, by changing the mole fraction of ethylene and α-olefin upon bringing a pre-catalyst and a monomer into contact with each other, the molecular weight distribution of the interpolymer can be controlled. The pre-catalyst is selected from the group consisting of a hydrocarbylamine substituted heteroaryl compound or a mixture thereof.
