Process for preparing compounds for tyres and tyres comprising them

Abstract

The present invention relates to a compound represented by the formula (II): CB-O-ROS-GC-Zn (II) where CB represents the white filler, O represents one or more oxygen bridge bonds, ROS represents an organo-silane residue, GC represents one or more coordinating groups forming a chelate with zinc in ionic form represented by linear, branched or cyclic alkyl chains, comprising one or more heteroatoms inside or at the end of the alkyl chain, and Zn represents zinc in ionic form coordinated with the coordinating groups, a process for the preparation thereof, and the use thereof in the vulcanisation process of elastomeric compounds.
