Se proporciona un aditivo a base de silano, formulaciones de caucho que incluyen el aditivo y neumáticos con bandas de rodadura fabricadas con dicho aditivo, junto con métodos para su formación. Las formulaciones de caucho sin curar, de acuerdo con las realizaciones preferidas de la invención, comprenden (1) un polímero primario o una mezcla de polímeros gomosos, como caucho natural o sintético; (2) una carga de sílice de refuerzo; (3) un monómero o polímero formador de red, especialmente una fracción termoendurecible formadora de red, para formar una red polimérica secundaria; y (4) un silano que contiene una o más fracciones del polímero formador de red mencionado anteriormente. En particular, se prefieren las redes que se pueden generar in situ. La formulación de caucho curado debe contener la sílice, con la red polimérica secundaria acoplada a ella, dentro de la matriz de caucho, y no directamente a las cadenas de caucho mediante enlaces sulfúricos.

    A silane based additive, rubber formulations including the additive and tires having tread portions made with the additive, together with methods of forming those products, are provided. Uncured rubber formulations in accordance with preferred embodiments of the invention comprise (1) a rubbery primary polymer or polymer blend, such as natural rubber and/or synthetic rubber; (2) reinforcing silica filler; (3) a network forming monomer or polymer, especially a thermosetting network forming moiety, for forming a secondary polymeric network; and (4) a silane containing one or more moieties of the aforementioned network forming polymer. In particular networks which can be generated in-situ are preferred. The cured rubber formulation should comprise the silica, having the secondary polymer network coupled thereto, within the rubber matrix, and not directly to the rubber chains via sulfidic linkages.
