Abstract
An object of the present invention is to provide a modified polymer that can realize a rubber composition having excellent low heat build-up and that has excellent productivity, a rubber composition containing the modified polymer, and a tire produced using the rubber composition. The modified polymer of the present invention is obtained by reacting a modifier having a nitrone group and a carboxy group with a conjugated diene polymer not containing a tetrasubstituted olefin and/or a trisubstituted olefin.
