Abstract
Coupling agents useful for preparing vulcanized composition with filers such as silica and carbon black are provided. The coupling agents include fluorine substituted styrene compounds and styrene compounds containing a hydrocarbyloxysilane functional group. The coupling agents may be grafted onto polydiene polymers or added into a vulcanizable composition as an oligomer. The use of one or both of fluorine substituted styrene compounds and styrene compounds containing a hydrocarbyloxysilane functional group may improve the strength, rolling resistance, and/or cure rate of a vulcanized polymer compared to a vulcanized polymer without a coupling agent.
