Title:
CATALYST FOR NORBORNENE MONOMER POLYMERIZATION AND METHOD FOR PRODUCING NORBORNENE POLYMER
Document Type and Number:
WIPO Patent Application WO/2012/053535
Kind Code:
A1
Abstract:
The present invention provides: a catalyst for norbornene monomer polymerization containing a transition metal complex (A) represented by general formula (1); and a method for producing, while in the presence of the catalyst for polymerization, a norbornene copolymer having a monomer unit represented by general formula (2) and general formula (3). (In the formulas, R1 and R2 represent a hydrogen atom or a C1-20 hydrocarbon group that may have a substituted group, R3, R4 and R5 represent a hydrogen atom or a C1-6 hydrocarbon group, R6 represents a C1-10 alkyl group, and R7, R8 and R9 represent a hydrogen atom or a C1-10 alkyl group.) The present invention makes it possible to efficiently produce a high molecular weight addition copolymer of a norbornene compound having a polar group.
