Title:
METHOD FOR PRODUCING CYCLIC OLEFIN-α-OLEFIN COPOLYMER
Document Type and Number:
Japanese Patent JP2013231096
Kind Code:
A
Abstract:

To provide a method for producing a cyclic olefin-α-olefin copolymer excellent in thermal decomposition resistance.

A method for producing a cyclic olefin-α-olefin copolymer involves copolymerizing a cyclic olefin and a 2-30C straight-chain α-olefin in a solution by using a polymerization catalyst obtained by a contact treatment of a transition metal compound having a cyclopentadiene-type anion skeleton, an aluminum compound and a boron compound, wherein the copolymerization is carried out in the presence of a specific vinyl compound in the solution containing an aluminum concentration of an aluminum atom originated from the aluminum compound of 2 to 15 mmol/L.
