RUBBER COMPOSITION AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition consisting of diene rubber polymers improving low heat generation properties without deteriorating reinforcing characteristics. SOLUTION: The rubber composition includes a diene rubber polymer (A) to which a carboxy group is introduced, and a diene rubber polymer (B) to which at least one kind of an amino group and a hydroxy group is introduced. A pneumatic tire using the rubber composition at least partially is also provided. COPYRIGHT: (C)2010,JPO&INPIT
