COUPLING AGENTS FOR ELASTOMERIC COMPOSITIONS. The present invention describes the use in an elastomeric composition which preferably comprises an isoprene elastomer, of an inorganic filler with a compound having the following formula (I), said compound of formula (I) being optionally, in whole or in part , in a polymerized form in which R is R6 or OR8, each of R1, R2, R3, R4, R5 and R6 is independently selected from: hydrogen and alkyl, aryl, alkaryl, aralkyl, cycloalkyl, heterocycloalkyl and alkenyl groups, and each of R7 and R8 is independently selected from: hydrogen and alkyl, aryl, alkaryl, aralkyl, cycloalkyl and alkenyl groups, and metals selected from the group consisting of Na, Li and Ca. |
