Abstract
An object of the present disclosure is to provide a terminal-modified conjugated diene polymer having a high cis-1,4 content and a low molecular weight distribution value and being excellent in durability (such as wear resistance, fracture resistance, cracking resistance, and the like). In order to achieve the object, a terminal-modified conjugated diene polymer of the present disclosure characteristically has: molecular weight distribution determined by gel permeation chromatography (GPC) of less than 2; and content of cis-1,4 bond of 95% or more.
