ABSTRACT:
A transition metal compound of Groups to 10 of the Periodic Table, represented by the following formula (1):wherein M represents a transition metal of Groups 8 to 10 of the Periodic Table; L, electrically neutral, represents a hetero atom-containing hydrocarbon group represented by the following formula (2)wherein R1to R5each independently represent a hydrogen atom, a halogen atom, a hydrocarbon group having form 1 to 20 carbon atoms, a halogenohydrocarbon group having from 1 to 20 carbon atoms, or a hetero atom-containing group, and optionally these groups are bonded to each other to form a ring; R6represents a hydrogen atom, a hydrocarbon group having form 1 to 40 carbon atoms, a halogenohydrocarbon group having from 1 to 40 carton atoms, or a hetero atom-containing group;L′ electrically neutral, represents a hetero atom-containing hydrocarbon group represented by the following formula (3)wherein R7to R11each independently represent a hydrogen atom, a halogen atom, a hydrocarbon group having from 1 to 20 carbon atoms, a halogenohydrocarbon group having from 1 to 20 carbon atoms, or a hetero atom-containing group, and optionally these groups are bonded to each other to form a ring;X represents a covalent-bonding or ionic-bonding group, and a plurality of X's are the same or different; Y represents an aromatic group-containing crosslinking group; Z is an integer of 1 or more, indicating the degree of polymerization of the compound; n indicates the atomic valency of M; and each of M, L, and Y are the same or different.
