Title:
PRODUCTION METHOD FOR CYCLIC OLEFIN COPOLYMER, AND CATALYST COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/120668
Kind Code:
A1
Abstract:
The present invention pertains to a production method for a cyclic olefin copolymer that contains a structural unit derived from a norbornene monomer and a structural unit derived from ethylene, the method at least comprising: a step for charging the norbornene monomer and ethylene as monomers into a polymerization vessel; and a step for polymerizing the monomers in the polymerization vessel in the presence of a catalyst having a phosphine imide group, wherein the catalyst having a phosphine imide group comprises a compound having a specific structure.
