Abstract

MODIFIED CONJUGATED DIENE-BASED POLYMER, RUBBER COMPOSITION AND TIRE A modified conjugated diene-based polymer, including a coupling polymer, wherein a ratio of the coupling polymer, obtained by gel permeation chromatography (GPC), is 30% by mass or more and less than 70% by mass in the entire modified conjugated diene-based polymer, and a modification ratio obtained by adsorption GPC is 30% by mass or more and less than 70% by mass in the entire modified conjugated diene-based polymer, when a peak top molecular weight, obtained by the GPC, of the coupling polymer of the modified conjugated diene-based polymer is represented by Mp1 and a peak top molecular weight of a non-coupling polymer is represented by Mp2, (Mp1/Mp2)  3.4, and a shrinking factor (g') is less than 0.60.
