  It now has been found that uncured modified rubber compositions comprising mixtures of elastomers and a reinforcing filler can be prepared having improved properties. More particularly, such uncured modified rubber compositions can be prepared by a process which comprises the steps of (A) preparing a first mixture comprising an elastomer, at least one reinforcing filler and at least one chemical agent capable of promoting the formation of filler-elastomer linkages; (B) preparing a second mixture comprising (i) an elastomer, at least one reinforc­ing filler and at least one chemical agent capable of promoting the forma­tion of filler-elastomer linkages, wherein at least one of the elastom­er, filler or chemical agent in the second mixture is different from the elastomer, filler or chemical agent in the first mixture; or (ii) an elastomer and at least one rein­forcing filler; or (iii) at least one reinforcing filler and at least one chemical agent capable of promoting the formation of fil­ler-elastomer linkages; or (iv) an elastomer and at least one chemi­cal agent capable of promoting the formation of filler-elastomer link­ages; and (C) blending the first and second mixtures to form a third mixture. Examples of such useful chemical agents include aromatic furazan oxides, heterocyclic di-N-oxides, 1-hydroxy-ben­zimidazole-3-oxide compounds, 1,3-dihydroxy-benzimidazol­inone compounds, and aromatic nitroso compounds. The invention also includes filled vulcanizates prepared by vulcanizing the uncured modified rubber com­positions prepared in accordance with the above method. Rubber articles and portions thereof made from such vul­canizates such as tires, hoses, belts, treads, sidewalls and the like are also within the scope of the present invention as well as methods of reducing the rolling resistance of tires.

  现在已经发现，由弹性体和补强填料混合物组成的未固化改性橡胶组合物可以制备出性能更好的产品。更具体地说，这种未固化改性橡胶组合物可通过以下步骤制备 (A) 制备第一种混合物，其中包括弹性体、至少一种补强填料和至少一种能够促进填料-弹性体连接形成的化学剂； (B) 制备第二种混合物，包括 (i) 弹性体、至少一种增强填料和至少一种能促进形成填料-弹性体联结 的化学剂，其中第二种混合物中的至少一种弹性体、填料或化学剂 不同于第一种混合物中的弹性体、填料或化学剂；或 (ii) 弹性体和至少一种增强填料；或 (iii) 至少一种增强填料和至少一种能促进填料-弹性体连接形成的化学剂；或 (iv) 弹性体和至少一种能促进形成填料-弹性体连接的化学剂；以及 (C) 混合第一和第二混合物，形成第三混合物。 此类有用化学剂的例子包括芳香族呋喃氧化物、杂环二-N-氧化物、1-羟基-苯并咪唑-3-氧化物化合物、1,3-二羟基-苯并咪唑啉酮化合物和芳香族亚硝基化合物。 本发明还包括通过硫化根据上述方法制备的未硫化改性橡胶组合物而制备的填充硫化胶。由此类硫化胶制成的橡胶制品及其部分，如轮胎、软管、皮带、胎面、侧壁等，以及降低轮胎滚动阻力的方法，也属于本发明的范围。
