Abstract
(EN)
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.
(FR)
La présente invention concerne un composé représenté par la formule (II) : CB-O-ROS-GC-Zn (II) où CB représente la charge blanche, O représente une ou plusieurs liaisons de pont oxygène, ROS représente un reste d'organo-silane, GC représente un ou plusieurs groupes de coordination formant un chélate avec du zinc sous forme ionique représentés par des chaînes alkyle linéaires, ramifiées ou cycliques, comprenant un ou plusieurs hétéroatomes à l'intérieur ou à l'extrémité de la chaîne alkyle, et Zn représente le zinc sous forme ionique lié par des liaisons de coordination aux groupes de coordination. La présente invention concerne également un procédé pour la préparation du composé et son utilisation dans le processus de vulcanisation de composés élastomères.
