Title:
TERMINALLY MODIFIED CONJUGATED DIENE POLYMER, RUBBER COMPOSITION, RUBBER PRODUCT, AND METHOD FOR PRODUCING TERMINALLY MODIFIED CONJUGATED DIENE POLYMER
Document Type and Number:
WIPO Patent Application WO/2017/203830
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a terminally modified conjugated diene polymer which has high cis-1, 4- bond content and low molecular weight distribution, while exhibiting excellent durability (wear resistance, fracture resistance, crack growth resistance and the like).
In order to achieve the above-described purpose, the present invention is characterized in that: the molecular weight distribution as determined by gel permeation chromatography (GPC) is less than 2; and the cis-1, 4- bond content is 95% or more.
