    • The invention relates to a rubber composition based on at least one diene elastomer, containing less than 0.5 phe of zinc, phe signifying parts per hundred parts of elastomer, and based on at least: one reinforcing filler; one sulphur-based crosslinking system, comprising a copper(II) carboxylate of formula: (RCOO)2Cu, in which R represents a hydrocarbon-based group chosen from linear or branched, cyclic or non-cyclic alkyls having from 1 to 20 carbon atoms, aryls, aralkyls or alkaryls having from 1 to 20 carbon atoms. Further subjects of the invention are a process for preparing a rubber composition according to the invention and the use of this composition for the manufacture of tires or of semi-finished products made of rubber intended for these tires.

    • A rubber composition usable for the manufacture of tyres, based on at least a diene elastomer, a reinforcing filler and a coupling agent, characterised in that said filler comprises a synthetic metal hydroxide covered with silica, the metal of the hydroxide being selected from the group consisting of Al, Fe, Mg and mixtures of these metals. Use as reinforcing filler, in a diene rubber composition, of such a metal hydroxide. The metal hydroxide is preferably constituted of aggregates (secondary particles) of anisometric form, the primary particles possibly themselves being of anisometric form, for example in the form of rods, which imparts to the compositions of the invention anisotropic properties which are advantageous for separating their mechanical properties. Use of such a rubber composition for the manufacture of rubber articles, in particular of tyres or semi-finished products made of rubber intended for these tyres, in particular of treads.
    • 一种可用于制造基于至少二烯弹性体,增强填料和偶联剂的轮胎的橡胶组合物,其特征在于所述填料包括用二氧化硅覆盖的合成金属氢氧化物,所述氢氧化物的金属选自 由Al,Fe,Mg和这些金属的混合物组成。 在二烯橡胶组合物中用作这种金属氢氧化物的增强填料。 金属氢氧化物优选由不等角度形式的聚集体(二次颗粒)构成,主要颗粒本身可以是不规则形式,例如以棒的形式,赋予本发明组合物各向异性特性,这有利于分离它们 机械性能。 使用这种橡胶组合物来制造橡胶制品,特别是用于这些轮胎的橡胶制成的轮胎或半成品,特别是胎面。
