Abstract
A composition of matter is disclosed that comprises at least one silane coupling agent for coupling an elastomer and a filler wherein said silane comprises at least one hydrolysable group that, upon compounding said silane with said elastomer and filler, is released to yield a compound that improves downstream processability of the compounded composition or the properties of the final rubber product or both.
