摘要：: PROBLEM TO BE SOLVED: To obtain a modified polymer by selectively introducing a nitroxide radical into the living terminal of a homopolymer or copolymer of a conjugated diene/or an aromatic vinyl compound. SOLUTION: The modified polymer is a homopolymer or copolymer of a conjugated diene/or an aromatic vinyl compound obtained by bonding an alkoxyamino compound represented by formula (I) (wherein R is at least one kind of C, O, N, S, P, a 1-30C alkylene group, and a 6-30 aryl group or a sing bond; R<SP>1</SP>to R<SP>3</SP>is each hydrogen, a 1-3C alkyl group or a 6-30C aryl group and one of R<SP>1</SP>to R<SP>3</SP>is at least a 6-30C aryl group; and A is a functional group capable of reacting with a carbon anion) to the living anion terminal of the homopolymer or copolymer by reaction.
