An organopolysiloxane is prepared by hydrolysis and polycondensation of an organosilicon compound in the presence of a liquid hydrolytic condensation catalyst which is separable. The organopolysiloxane contains a high proportion of cyclic polysiloxanes and has a sharp molecular weight distribution due to minimized monomer and polymer contents.
