RING-OPENING METATHESIS POLYMERIZATION CATALYST AND METHOD FOR PRODUCING RING-OPENING METATHESIS POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a ring-opening metathesis polymerization catalyst capable of regulating ring-opening metathesis polymerization, having sufficiently high catalytic activities and capable of being produced industrially inexpensively; and to provide a method for producing a ring-opening metathesis polymer by using the polymerization catalyst.;SOLUTION: The ring-opening metathesis polymerization catalyst comprises a transition metal alkylidene complex represented by general formula (1) (wherein, M is a group 5 transition metal in the periodic table; R¹ is a 1-20C alkyl, aryl or arylalkyl group; R² is a 1-20C alkyl, aryl or arylalkyl group; R³ and R⁴ are each hydrogen, a 1-20C alkyl, aryl, arylalkyl or alkylsilyl group; and E is a ligand comprising an electron-donating compound including an amine, pyridine, phosphine, an ether or a thioether).;COPYRIGHT: (C)2008,JPO&INPIT
