摘要： A highly productive, continuous method for the production of room-temperature-curable organopolysiloxane compositions is obtained by continuously feeding 100 parts by weight of a diorganopolysiloxane with a viscosity at 25.degree. C. of 0.1 to 500 Pa.s that contains at least 2 silicon-bonded hydroxyl groups or hydrolyzable groups in each molecule; 1 to 30 parts by weight of an organosilane that contains at least 2 silicon-bonded hydrolyzable groups in each molecule, or the partial hydrolysis condensate thereof; 1 to 200 parts by weight of an inorganic filler in powder form, and 0 to 10 parts by weight of a cure-accelerating catalyst into a continuous mixing apparatus having starting material feed openings installed at its top, a discharge opening installed at its bottom, and a rotating disk installed within a casing and are therein mixed by the rotation of the said rotating disk, and in that the resulting mixture is thereafter continuously introduced into a vacuum mechanism- equipped degassing apparatus in which the water fraction present in the said mixture is removed under reduced pressure.
