Abstract: A hydrosilation process where a siloxyhydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an accelerator selected from a group consisting of acetylenic alcohols and acetylenic ethers. The accelerators are especially useful for the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene and cyclohexene.

Abstract: A hydrosilation process where a silicon hydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an aldehyde accelerator. The aldehyde accelerators are especially useful for facilitating the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene and cyclohexene.

Abstract: A hydrosilation process where a silicon hydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an accelerator selected from a group consisting of unsaturated secondary and tertiary alcohols and silated unsaturated secondary and tertiary alcohols. The accelerators are especially useful for the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene and cyclohexene. The accelerators are believed to be effective in the presence or absence of oxygen.

Abstract: A hydrosilation process where a silicon hydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an accelerator selected from a group consisting of tertiary alcohols, silated tertiary alcohols, benzyl alcohol, and silated benzyl alcohol. The accelerators are especially useful for the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene and cyclohexene. The accelerators are believed to be effective in the presence or absence of oxygen.

Abstract: A process for preparing a cured, fiber-reinforced composite comprises (I) blending an aminofunctional silicone resin containing monophenyl siloxy units and aminofunctional siloxy units, an epoxy resin and a hardener for the epoxy resin such as an aromatic diamine, (II) impregnating reinforcing fibers with the blend, (III) laying up at least two layers of the impregnated fibers, and (IV) heating the layed-up laminate at a temperature and time sufficient to cure the epoxy resin.

Abstract: A cured, fiber-reinforced composite is prepared by blending an amino-functional silicone resin containing monophenyl siloxy units and amino-functional siloxy units, an epoxy resin, a hardener for the epoxy resin and an aromatic oligomer such as a polyether optionally with reactive primary amine groups, impregnating fibers into said blend, laying up at least two layers of the impregnated fibers, and heating the layed-up laminate at a temperature and time sufficient to cure the epoxy resin.

Abstract: A hydrosilation process where a silicon hydride is reacted with an unsaturated reactant in the presence of a platinum catalyst and an unsaturated ketone accelerator. The described unsaturated ketone accelerators are especially useful for the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene and cyclohexene. The unsaturated ketone accelerators are effective in the absence of oxygen activation of the platinum catalyst and are synergetic with oxygen activation of platinum catalyst.

Abstract: The present invention is a method for the preparation of carbinol-functional organosiloxanes and carbinol-functional organosiloxane resins. The method comprises contacting a cyclic silyl ether with an organosiloxane or an organosiloxane resin at a temperature within a range of about 25.degree. C. to 150.degree. C. The method may be conducted in the presence of an inert organic solvent to facilitate dissolution and contact of the reactants.

Abstract: This invention relates to certain new high modulus silicones, toughened epoxy thermoset resin systems made from those silicones, and composites that are prepared from the new toughened epoxy resin systems. The silicone resins are specifically monophenyl-containing polysiloxanes.
