RUBBER COMPOSITION AND TIRE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition improving grip performances and abrasion resistance and to provide a tire using the rubber composition. SOLUTION: The rubber composition comprises a thermoplastic polyurethane obtained by using a conjugated diene polymer modified at both ends thereof with hydroxy groups or an aromatic vinyl-conjugated diene copolymer modified at both ends thereof with hydroxy groups in amount of 0.5-150 pts.wt. based on 100 pts.wt. of a rubber component composed of a diene-based rubber. The tire is obtained by using the rubber composition. COPYRIGHT: (C)2008,JPO&INPIT
