摘要：The present invention provides a modified polymer, which is obtained by reacting, with an active metal bonded to a polymer, a modifier represented by the general formula (I) (where X1 to X5 each represent a hydrogen atom or a specific monovalent functional group, and at least one of those is other than a hydrogen atom, R1 to R5 each represent a single bond or a divalent hydrocarbon group having 1 to 18 carbon atoms, and a plurality of aziridine rings may be bonded through any of X1 to X5 and R1 to R5). More particularly, the present invention provides a novel modified polymer which has excellent interaction with carbon black and enables improvement in dispersibility of the carbon black when used in a rubber composition blended with the carbon black, a rubber composition containing the modified polymer and capable of providing a tire excellent in low heat generating property, rupture characteristics, and abrasion resistance, and a tire made of the rubber composition and having the above-mentioned characteristics.
