    摘要： A process for producing a cured silsesquioxane resin. The process includes fractionating the silsesquioxane resin a plurality of times utilizing an organic solvent in combination with an organic non-solvent. The fractionated resin is then stripped of excess solvent. The stripped resin is then mixed with a cross-linking compound to form a curable composition. The curable composition is cured to form a cured resin having high fracture toughness and strength without the loss of elastic modulus.

    摘要： Compositions curable by exposure to UV or electron beam are disclosed which contain mercapto functional organosiloxanes and organosiloxanes bearing alkenyl groups with 6 or more carbon atoms. The compositions cure upon irradiation without the emission of obnoxious odor which characterizes the analogous composition of the art containing olefinic siloxanes having only vinyl unsaturation. Also disclosed is a method of treating a substrate with the coating composition to improve the release of adhesive materials therefrom.
