摘要 |
The invention relates to the use of a combination (i) of a member of a group of coupling agents based on organosilanes of formula (I), each with a double ethylenic bond activated (2i) with a very small quantity of a coupling activator consisting especially of an organic peroxide; as a white filler-elastomer coupling system in dienic rubber compositions (s) containing a white filler, especially a siliceous white filler, as a reinforcing filler. The organosilanes correspond to formula (I) (R1O)n(R2)3-aSiZ, wherein R1 and R2 are monovalent hydrocarbonated groups, a is a number chosen from 1, 2 and 3, and Z is a function containing an activated ethylenic double bond, chosen especially from a maleamic acid, acrylamide, acrylic or isomaleimide function. |
