Claim 5:
6. A method for producing the ethylene/α-olefin/non-conjugated polyene IS) copolymer according to claim 1, comprising:
(1) a step of carrying out the copolymerization in the presence of a polymerization catalyst containing at least one metallocene compound represented by the following general formula [A1] and (2) a step of adding an alcohol as a catalyst deactivator to deactivate the polymerization catalyst;, wherein R1, R2, R3, R4, R5, R8, R9 and R12 each independently represent a hydrogen atom, a hydrocarbon group, a silicon-containing group, or a heteroatom-containing group other than the silicon-containing group, and any two adjacent groups of R1 to R4 may be bonded to each other to form a ring;
R6 and R11 are the same atom or the same group selected from a hydrogen atom, a hydrocarbon group, a silicon-containing group, and a heteroatom-containing group other than the silicon-containing group, and R7 and R10 are the same atom or the same group selected from a hydrogen atom, a hydrocarbon group, a silicon-containing group, and a heteroatom-containing group other than the silicon-containing group, and R6 and R7 ay be bonded to each other to form a ring, and R10and R11 may be bonded to each other to form a ring, provided that all of R6, R7, R10, and R11 are not a hydrogen atom;
R13 and R14 ach independently represent an aryl group;
M1 represents a zirconium atom;
Y1 represents a carbon atom or a silicon atom;
Q represents a halogen atom, a hydrocarbon group, a halogenated hydrocarbon group, a neutral conjugated or non-conjugated diene having 4 to 20 carbon atoms, an anionic ligand, or a neutral ligand capable of coordinating with a lone pair, j represents an integer of 1 to 4, and when j is an integer of 2 or more, each Q may be the same or different from each other.
