Conjugated Diene-Based Polymer, Formed Body, Production Method for Conjugated Diene-Based Polymer, Rubber Composition, and Tire

Abstract

A conjugated diene-based polymer, satisfying the following <condition (i)> to <condition (iii)>: <condition (i)> a Mooney viscosity measured at 100° C. is 80 or more and 170 or less; <condition (ii)> a Mooney stress relaxation (MSR) measured at 100° C. is 0.30 or more and 0.80 or less; and <condition (iii)> the polymer has an extreme value that is convex downward in a branch number distribution curve indicating a relationship between an absolute molecular weight and a branch number (Bn), as measured by viscosity detector-equipped GPC-light scattering measurement.
