Title:
触媒組成物、触媒組成物を用いたノルボルネン系共重合体の製造方法、及びノルボルネン系共重合体、更には、その共重合体を用いた耐熱性フイル
Document Type and Number:
Japanese Patent JP5828700
Kind Code:
B2
Abstract:
Provided are a catalyst composition for efficiently obtaining a high molecular weight addition copolymer of a norbornene compound having a polar group, a process for producing a high molecular weight addition copolymer of a norbornene compound by using the above catalyst composition, a copolymer thereof and a film prepared by using the above copolymer. It is a catalyst composition comprising a main catalyst (A) and a promoter (B) which are used for copolymerization of norbornene having a polar group, wherein the main catalyst (A) is a complex represented by Formula (1): €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒML n K1 x K2 y K z €ƒ€ƒ€ƒ€ƒ€ƒ(1) (wherein M is one transition metal selected from group 8 elements, group 9 elements and group 10 elements in the periodic table; L is a cyclopentadienyl base ligand containing a cyclopentadiene ring; K1, K2 and K3 are anionic ligands or neutral ligands which are different from each other; n is an integer of 0 to 2; x, y and z each are an integer including 0, and a sum thereof is 1 to 7); and the promoter (B) is an ionic compound (a) which can be reacted with the main catalyst (A) to form a cationic transition metal compound.
