Abstract: The invention relates to a process for preparing polyorganosiloxanes which comprise substantially no cyclic components and have uniform molecular weight distribution by reacting organosilicon compounds which have no condensable groups in the presence of a catalyst which exclusively promotes equilibration and suppresses formation of cyclic components. The resulting polyorganosiloxanes have a linear or branched structure. They can either be used immediately, for example in silicone rubbers and silicone greases, as components in release agents, in impregnating agents, in antifoams, etc., or are starting compounds for preparing organofunctionally modified polysiloxanes which are obtained by hydrosilylation of the polyorganosiloxanes with hydrocarbons and/or organic polymers.
