Diorganopolysiloxanes with triorganosiloxy groups as terminal units are prepared in that the diorganopolysiloxanes, which may already have triorganosiloxy groups, after they have reached the desired average viscosity by condensation and / or equilibration in the presence of catalysts other than phosphonitrile chloride, with hexaorganodisilazane in amounts of 0.05 to 2 Percentage by weight, based on the weight of the amount of diorganopolysiloxane used, are mixed and after this mixing, phosphorus nitride chloride is added as a catalyst for the reaction. |
