Title:
ノルボルネン系モノマー重合用触媒及びノルボルネン系重合体の製造方法
Document Type and Number:
Japanese Patent JP5834017
Kind Code:
B2
Abstract:
The invention relates to a catalyst for the polymerization of norbornene monomers comprising transition metal complex (A) represented by formula (1); and a method for producing a norbornene (co)polymer, especially a norbornene copolymer containing a monomer unit represented by formulae (2) and (3), wherein a norbornen monomer is homopolyzed or copolymerized in the presence of the polymerization catalyst. Preferable examples of the transition metal complex (A) include (À-allyl){4-(2,6-diisopropylphenylimino)-2-penten-2-olato- º 2 N,O}palladium and (À-allyl){4-(1-naphthylimino)-2-penten-2-olato- º 2 N,O}palladium. 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.
