Method for producing a norbornene-based monomer polymerization catalyst and norbornene-based polymer

摘要

Transition metal complex represented by the general formula (1) norbornene polymerization catalyst containing (A), and the presence of the polymerization catalyst, norbornene to homopolymerization or copolymerization of norbornene-based monomer present invention (co providing) polymer, a method for producing a norbornene-based copolymer having a monomer unit represented by the general formula (2) formula (3) in particular. Transition metal complexes as (A), (π- allyl) {4-(2,6-diisopropylphenyl-imino)-2-penten-2-olato -κ ² N, O} palladium, (π- allyl) and {4 - (1 Nafuchiruimino)-2-penten-2-olato -κ ² N, O} palladium is preferred. (Symbols in the formula,. As described herein) In accordance with the present invention, it is possible to efficiently produce norbornene having excellent transparency, heat resistance, low water absorption, the electrical insulation properties of the (co) polymer.
