  • .alpha., .beta.-unsaturated carbonyl-functional silicone compositions
    Patent number: 4725630
    Abstract: Polymerizable .alpha., .beta.-unsaturated carbonyl-functional silicone compositions are obtained from the reaction of thiol-functional organopolysiloxanes with an .alpha., .beta.-unsaturated carbonyl-functional compound having at least two acryloyl or methacryloyl groups or mixtures thereof per molecule in the presence of a base catalyst.The .alpha., .beta.-unsaturatured carbonyl-functional silicone compositions may be combined with a photosensitizer and/or a free radical generator and polymerized by radiation and/or heat.

  • Heat curable organopolysiloxane compositions
    Patent number: 4710559
    Abstract: Heat curable organopolysiloxane compositions comprising an organopolysiloxane having Si-bonded aliphatically unsaturated groups, an organohydrogenpolysiloxane having Si-bonded hydrogen atoms, a platinum catalyst capable of promoting the addition of Si-bonded hydrogen to Si-bonded aliphatically unsaturated groups and a hydrazone compound. The resultant composition is stable at room temperature, but when heated to an elevated temperature cures to an elastomer.
