RUBBER COMPOSITION RESISTANT TO PERMANENT SET IN FATIGUE AND PNEUMATIC TIRE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition improved in resistance to permanent set in fatigue. SOLUTION: This rubber composition, resistant to permanent set in fatigue, is prepared by compounding 100 ps.wt. rubber component comprising at least one rubber selected from among natural and diene synthetic rubbers with 30-100 pts.wt. reinforcing filler and 0.2-3.0 pts.wt. specific diphenylamine age resister.
