| Abstract: | The effect of nine derivatives of salicylanilides on the elastic properties of ultraviolet-aged natural rubber have been investigated. The results are compared with similar blends without additives and also with reference samples containing phenyl salicylate. The compounds showed variable effects, but both o-Cl and p-OCH3 derivatives showed remarkable effects. They both help in the thermal crosslinking. Also, natural rubber samples containing these derivatives showed remarkable stability in tensile stress, elongation, and swelling. |
