Abstract
A vulcanizable elastomeric composition and a method of forming said composition is presented. The method generally comprises the mixing of sulfur and an ultra-accelerator into a mixture of an elastomeric polymer matrix, fillers, and silane coupling agent during the silanization reaction step, prior to the occurrence of vulcanization. The addition of the ultra-accelerator, such as TBzTD, enhances the efficiency of the silanization reaction and forms at least one bond with the elastomeric polymer matrix. The silanization reaction step may comprise multiple mixing substeps in which the ultra-accelerator may be incorporated into the elastomeric composition.
