Patent

CA 2520910

A composition of matter is disclosed that comprises at least one silane coupling agent for coupling an elastomer and a filler wherein said silane comprises at least one hydrolysable group that, upon compounding said silane with said elastomer and filler, is released to yield a compound that improves downstream processability of the compounded composition or the properties of the final rubber product or both.

L'invention concerne une composition de matière contenant au moins un agent de couplage silane destiné à coupler un élastomère et une charge, ledit silane contenant au moins un groupe hydrolysable qui est libéré pendant le mélangeage du silane avec l'élastomère et la charge, de sorte à produire un composé permettant d'améliorer l'aptitude au traitement en aval de la composition résultante ou les propriétés du produit final en caoutchouc, ou les deux à la fois.
