Title:
CATALYST FOR NORBORNENE MONOMER POLYMERIZATION AND METHOD FOR PRODUCING NORBORNENE POLYMER
Document Type and Number:
WIPO Patent Application WO/2012/057135
Kind Code:
A1
Abstract:
The present invention provides: a catalyst for norbornene polymerization, which contains a transition metal complex (A) that is represented by general formula (1); and a method for producing a norbornene (co)polymer, especially a norbornene copolymer having monomer units that are represented by general formula (2) and general formula (3), wherein a norbornene monomer is homopolymerized or copolymerized in the presence of the polymerization catalyst. Preferable examples of the transition metal complex (A) include (π-allyl){4-(2,6- diisopropylphenylimino)-2-penten-2-olato-κ
2N,O}pallarium and (π-allyl){4-(1-naphthylimino)-2-penten-2-olato- κ
2N,O}pallarium.
(In the formulae, the symbols are as defined in the description.)
A norbornene (co)polymer which has excellent transparency, excellent heat resistance, excellently low water absorption and excellent electrical insulation characteristics can be efficiently produced by the present invention.
