Abstract
A composition is provided for use with an unsaturated elastomer. The composition may include a sulfur-functional linear polyorganosiloxane. The sulfur-functional linear polyorganosiloxane may include a chemically protected sulfur group. Under certain conditions, the sulfur group may react with the unsaturated elastomer. The invention includes embodiments that may relate to methods of making and using the sulfur-functional linear polyorganosiloxane in elastomer compositions.
