BUTILA RUBBER COMPOUNDS UNDERSTANDING A MODIFIER SYSTEM OF THREE MIXED COMPONENTS, AND THEIR PREPARATION PROCESS. The present invention relates to rubber compounds containing a halobutyl elastomer, at least one additional elastomer, a mineral filler and at least one three-component mixed modifier system comprising a silane, a phosphine and an additive comprising at least one hydroxyl group. and a functional group comprising a basic amine. Also described is a process for preparing said compounds. The compounds are particularly useful in tire treads, and exhibit improved properties of processability, traction, rolling resistance and wear. |
