METHOD FOR PRODUCING PROPYLENE/α-OLEFIN COPOLYMER

Title:

METHOD FOR PRODUCING PROPYLENE/α-OLEFIN COPOLYMER

Document Type and Number:

Japanese Patent JP2019172944

Kind Code:

A

Abstract:

To provide a method for producing a propylene copolymer with a high molecular weight without depending on improvement of transition metal compounds used for polymerization catalysts.SOLUTION: A method for producing a propylene/α-olefin copolymer has a polymerization step of polymerizing propylene and α-olefin (excluding propylene) in the presence of a catalyst for olefin polymerization containing a predetermined transition metal compound (A), and a carrier (B) comprising a predetermined solid polyaluminoxane composition carrying the transition metal compound (A).SELECTED DRAWING: None
