Abstract of the Disclosure RUBBER STOCK CONTAINING PHENOXYACETIC ACID The present invention relates to a rubber stock containing 0.1 to 10.0 phr of phenoxyacetic acid. Addition of the phenoxyacetic acid to a rubber stock increases the low strain stiffness properties of the rubber stock and results in increased treadwear when the stock is used in tread stocks. The phenoxyacetic acid may also be used in a rubber stock as a methylene acceptor or resorcinol replacement. In addition, the phenoxyacetic acid functions as a silica coupling agent and provides lower viscosities for processing the rubber stock compared to rubber stocks containing conventional silane coupling agents.
