    Abstract: Alkoxy-modified silsesquioxane compounds are described. The alkoxy-modified silsesquioxane compounds contain an alkoxysilane group that participates in an alkoxysilane-silica reaction as a silica dispersing agent in rubber, with the release of zero to about 0.1% by weight of the rubber of volatile organic compounds (VOC), especially alcohol, during compounding and further processing. Further described are methods for making alkoxy-modified silsesquioxanes, methods for making vulcanizable rubber compounds containing alkoxy-modified silsesquioxanes, vulcanizable rubber compounds containing alkoxy-modified silsesquioxanes, and pneumatic tires comprising a component that contains alkoxy-modified silsesquioxanes.

  • Publication number: 20110118495
    Abstract: Cardanol based dimers are provided. The cardanol dimers are formed by hydrosylylation with silanes. Cardanol based dimers may be further reacted to form epoxy curing agents and epoxies which can be used as anti-fouling coatings on ship hulls and marine structures. The cardanol dimers may also be used to produce friction particles or phenolic resins. Methods of synthesizing the cardanol based dimers, the epoxy curing agents and the epoxies are also provided.
