    摘要: A process for the preparation of a rubber compound for a pneumatic tyre portion. The process comprises a first non-productive mixing step, wherein, at least one cross-linkable unsaturated-chain polymer base, silica, a silane bonding agent comprised within the class of trialkoxymercaptoalkyl-silanes are mixed together and a productive mixing step, wherein, at least a vulcanization system and Zn oxide are added and blended to the compound under preparation. The silica is functionalized with dicarboxylic acids and the first non-productive mixing step does not comprise Zn oxide.
