  • Vinyl carbosiloxane resins
    Patent number: 9556313
    Abstract: This invention is a vinylcarbosiloxane resin that is the hydrosilation reaction product of 1,3,5,7 -tetravinyl-1,3,5,7-tetramethylcyclotetrasiloxane and a hydride-terminated linear polysiloxane, siloxane, or silane, having two terminal Si—H hydrogens reactive with vinyl groups in a hydrosilation reaction, in the presence of a platinum catalyst. Suitable hydride-terminated linear polysiloxanes, siloxances, and silanes include those having the structures: In another embodiment, the vinylcarbosiloxane resin can be reacted with one or more other hydrido-silanes and hydrido-polysiloxanes in the presence of a platinum catalyst to form a curable composition.
