POLYMER MODIFIED WITH FUNCTIONAL TERMINAL GROUP BASED ON CONJUGATED DIENE OR BASED ON CONJUGATED DIENE AND VINYL AROMATIC COMPOUND, MANUFACTURING METHOD OF THE SAME, AND MOLDING COMPRISING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polymer which shows an improvement in processability along with improved physical properties and dynamic properties, to provide a manufacturing method thereof, and to provide the use thereof for manufacture of all the types of rubber moldings, particularly for the manufacture of tires and tire-constituting materials such as tire treads.;SOLUTION: The polymer is modified with a functional terminal group, and is based on a conjugated diene or based on a conjugated diene and a vinyl aromatic compound, and has an average mol.wt. (Mw) exceeding 10,000 g/mol and a mol.wt. distribution (Mn/Mw) of 1.3-5.;COPYRIGHT: (C)2003,JPO
