Title: MODIFIED CONJUGATED DIENE POLYMER, METHOD FOR PRODUCING SAME, RUBBER COMPOSITION, AND TIRE
Abstract:
A modified conjugated diene polymer having nitrogen atoms, wherein the modified conjugated diene polymer has a nitrogen atom content of 25 mass ppm or higher relative to the total amount of the modified conjugated diene polymer, a shrinkage factor (g') of 0.59 or lower as measured through a GPC-light scattering measurement method with a viscosity detector, and a weight-average molecular weight of 200,000-3,000,000.
