RUBBER COMPOSITION FOR TIRE SIDEWALL

摘要

PURPOSE:To obtain the subject composition having excellent ozone-degradation resistance, adhesiveness, co-vulcanizability, breaking strength and flexural fatigue resistance by compounding a specific compound to a specific diene rubber component. CONSTITUTION:The objective composition is produced by compounding (A) 100 pts.wt. of a diene rubber component containing >=30 pts.wt. of an ethylene- propylene-diene polymer rubber having a Mooney viscosity of >=110 at l00 deg.C and an iodine value of 24-35 with (B) preferably 0.1-5.0 pts.wt. of a compound of formula [Z is RNH (R is 1-18C aliphatic or cycloaliphatic group); R1 and R2 are H or 1-12C alkyl; R1 and R2 may together form a ring].
