  • Patent number: 8119746
    Abstract: This application relates to polysiloxane compositions grafted with improved heat curable, moisture curable, or heat/moisture curable groups. In particular, the polysiloxane compositions have reactive groups on the terminal or pendent areas of the siloxane backbone, which once reacted provide improved heat and/or moisture curable polysiloxanes.

  • Patent number: 6140444
    Abstract: The invention relates to a catalyst system for reacting a silanol group with an alkoxysilane containing a polymerizable ethylenically unsaturated group. The catalyst system includes an organo-lithium reagent and a hydroxylamine. The catalyst system, permits reaction of the silanol group with alkoxysilanes containing rapidly polymerizable ethylenically unsaturated groups, such as an acryloxyalkyl group, for instance an acryloxypropyl group.
