Title
(EN) POLYMER NETWORK FORMING SILANE COMPOSITIONS
(FR) COMPOSITIONS DE SILANE FORMANT DES RÉSEAUX POLYMÈRES
Abstract
(EN)
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.
(FR)
L'invention concerne un additif à base de silane, des compositions de caoutchouc comprenant l'additif et des pneus comportant des parties de bande de roulement fabriquées avec l'additif, ainsi que des procédés de fabrication de ces produits. Les compositions de caoutchouc non durci conformes à des modes de réalisation préférés de l'invention comprennent (1) un polymère primaire ou un mélange de polymères caoutchouteux , tel que du caoutchouc naturel et/ou du caoutchouc synthétique ; (2) une charge de renforcement à base de silice ; (3) un monomère ou un polymère formant un réseau, en particulier une fraction formant un réseau thermodurcissable, pour former un réseau polymère secondaire ; et (4) un silane contenant une ou plusieurs fractions du polymère formant un réseau susmentionné. Des réseaux qui peuvent être générés in situ sont, en particulier, préférés. La composition de caoutchouc durci doit comprendre la silice, à laquelle est couplé le réseau polymère secondaire, au sein de la matrice de caoutchouc, le couplage ne devant pas se faire directement avec les chaînes de caoutchouc par l'intermédiaire de liaisons sulfidiques.
