  It now has been found that the properties of rubber compositions comprising rubbers having an unsaturated carbon chain can be improved by including therein, a minor property-improving amount of at least one hydroxy-benzimidazole oxide compound of the formula wherein R is hydrogen, or a halogen, hydroxyl, lower acyl, lower hydrocarbyl, lower hydrocarbyloxy, lower hydrocarbylthio, carboxyl, cyano, amino, amide or -C(O)- ­lower hydrocarbyl group, and Rʹ is hydrogen, or a lower hydrocarbyl, lower hydrocarbyl amide, carboxamide carboxy acid, carboxy ester, or aryl group. When vulcanizates are prepared from such rubber compositions containing one or more fillers, the vulcanizates exhibit reduced low strain hysteresis and a high electrical resistivity. In another aspect of the invention, a filled vulcanizate made by vulcanizing uncured compositions of the type described above and containing a filler, particularly carbon black, is improved in filler interaction, hysteresis, modulus, compression set and resiliency. Rubber articles and portions thereof such as tires, hoses, springs, belts, treads, sidewalls and the like can be made utilizing the improved filled vulcanizates of the invention.

  现已发现，通过在橡胶组合物中加入少量的至少一种羟基氧化苯并咪唑化合物，可改善橡胶组合物的性能，该化合物具有不饱和碳链 其中 R 是氢、或卤素、羟基、低级酰基、低级烃基、低级烃氧基、低级烃硫基、羧基、氰基、氨基、酰胺或 -C(O)- 低级烃基，Rʹ 是氢、或低级烃基、低级烃酰胺、羧酰胺、羧酸、羧酸酯或芳基。当用含有一种或多种填料的此类橡胶组合物制备硫化胶时，硫化胶表现出较低的应变滞后性和较高的电阻率。 在本发明的另一个方面，通过硫化上述类型的未硫化组合物和含有填料（尤其是炭黑）的填充硫化胶，可改善填料相互作用、滞后、模量、压缩永久变形和回弹性。利用本发明的改进型填充硫化胶，可制成橡胶制品及其部分，如轮胎、软管、弹簧、皮带、胎面、侧壁等。
