  • Asymmetrical siloxy disulfide compounds
    Patent number: 6727374
    Abstract: The present invention relates to asymmetrical siloxy compounds of the formula wherein R1, R2 and R3 are independently selected from the group consisting of alkoxy radicals having from 1 to 8 carbon atoms; and R4 is selected from the group consisting of substituted or unsubstituted alkylene groups having from 1 to 18 carbon atoms and arylene and alkyl substituted arylene groups having from 6 to 12 carbon atoms. The asymmetrical siloxy disulfide compounds are prepared from N-cyclohexylthiophthalimide and a mercaptoalkoxysilane.

  • SILICA REINFORCED RUBBER COMPOSITION WHICH CONTAINS STABILIZED UNSYMMETRICAL COUPLING AGENTS AND ARTICLE OF MANUFACTURE, INCLUDING A TIRE, HAVING AT LEAST ONE COMPONENT COMPRISED OF SUCH RUBBER COMPOSITION
    Patent number: 6465581
    Abstract: This invention relates to use of stabilized unsymmetrical coupling agents for use in conjugated diene-based rubber compositions reinforced with silica-based reinforcement, namely use of stabilized 2-benzothiazyl-3-(triethoxysilylpropyl) disulfide and 3-(triethoxysilyl)propyl-N-maleamic acid. Said stabilized unsymmetrical coupling agent materials may be provided for mixing with said diene-based rubber(s), for example, as individual materials, as at least one of said materials being pre-reacted with aggregates of precipitated silica, said precipitated silica having hydroxyl groups (e.g. silanol groups) on its surface. The invention includes an article of manufacture, including a tire, having at least one component comprised of such rubber composition.
