    摘要: Disclosed is an organosiloxane polymer-based composition curable by the mechanism of the hydrosilation reaction between silicon-bonded vinyl groups in a vinylsilyl-terminated perfluoropolyalkylene or perfluoropolyalkylene polyether compound and silicon-bonded hydrogen atoms in a hydrosilyl-terminated perfluoropolyalkylene or perfluoropolyalkylene polyether compound as promoted by a catalyst. Different from conventional platinum compounds as the catalyst for the hydrosilation reaction, the catalyst in the inventive composition is a complex compound of rhodium such as tris(triphenylphosphine) rhodium chloride, rhodium acetate dimer and rhodium acetylacetonate so that the composition is imparted with greatly improved storage stability without viscosity increase over months at room temperature but without affectibg the curability at an elevated temperature.
