    摘要: Novel siloxane compounds are provided which have 1-5 hydrogen atoms each attached to a silicon atom (SiH group) and 1-5 epoxy or alkoxy - containing organic groups each attached to a silicon atom in a molecule. These siloxane compounds are useful tackifiers to conventional resins, have good affinity to fluorinated silicone resins and rubbers so that they impart adhesion to fluorinated silicone resins and rubbers, and contribute to solvent resistance and minimal moisture permeability.

    摘要: A novel and very efficient method is disclosed for the introduction of perfluoroalkyl groups into an organopolysiloxane by utilizing the hydrosilation reaction with an organohydrogenpolysiloxane. Different from the conventional but inefficient hydrosilation reaction using a perfluoroalkyl-substituted ethylene as the olefin compound, the inventive method utilizes a propene-1 3-substituted by a perfluoroalkyl group compound as the olefin compound to react with an organohydrogenpolysiloxane by which a very high efficiency in the hydrosilation reaction can be obtained without side reactions which otherwise greatly decrease the yield of the desired perfluoroalkyl-containing organopolysiloxane product.
