Abstract
An improved elastomeric composition comprising an elastomer (e.g. a natural or synthetic rubber), a filler, and a coupling agent for coupling the elastomer to the filler is provided wherein the coupling agent comprises at least one silane and at least one succinimide. The filler preferably comprises a silica and the succinimide preferably is an alkenyl succinimide, especially an alkenyl succinimide which is the condensation product of a polyamine with an alkenyl succinic anhydride, the alkenyl portion of which has 3 to 100 carbon atoms. The use of silane and succinimide for coupling provides elastomer/filler compositions having highly desirable dynamic and static properties at a more acceptable price and odor level than possible using the silane alone as coupling agent.
