Title:
CONJUGATED DIENE POLYMER, PROCESS FOR PRODUCING CONJUGATED DIENE POLYMER, CONJUGATED DIENE POLYMER COMPOSITION AND PROCESS FOR PRODUCING CONJUGATED DIENE POLYMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2008/032417
Kind Code:
A1
Abstract:
It is intended to provide a conjugated diene polymer, a process for producing the conjugated diene polymer, a conjugated diene polymer composition and a process for producing the conjugated diene polymer composition. The conjugated diene polymer is a conjugated diene polymer having a conjugated diene-based monomer unit and a group represented by the formula (I), wherein assuming the whole area of the molecular weight distribution curve obtained by gel permeation chromatography as 100%, the peak area of the molecular weight peak at the lowest molecular weight is 50% or more. [In the formula, R1 and R2 each independently represent a hydrocarbon group, a hydrocarbon oxy group or a hydroxyl group, m represents an integer of 0 to 10, and A1 represents a polar functional group free of an active hydrogen atom.]
