发明名称 RUBBER COMPOSITION CONTAINING N-(4-HYDROXYPHENYL)STEARIC ACID AMIDE
摘要 PROBLEM TO BE SOLVED: To obtain a rubber composition for providing a cured rubber having improved physical properties. SOLUTION: This method for preparing a rubber composition characteristically comprises mixing (i) 100 pts.wt. of at least one kind of olefin unsaturated elastomer selected from the group consisting of a natural rubber, a conjugated diene homopolymer and copolymer and a copolymer of at least one kind of a conjugated diene and an aromatic vinyl compound with (ii) 0.05-10 phr of N-(4-hydroxyphenyl)stearic acid amide. The rubber composition characteristically comprises the olefin unsaturated elastomer and 0.05-10 phr of N-(4- hydroxyphenyl)stearic acid amide. The presence of N-(4-hydroxyphenyl)stearic acid improves physical properties including flexural fatigue durability.
