摘要

The present invention is directed to a process for the preparation of organopolysiloxanes by reacting linear siloxane compounds (ii) and / or cyclic siloxane compounds (iii) with an at least one compound having hydroxyl - group r ''- oh (iv), with r'' are identical or different organic radicals, which is characterized in that the compounds of the formula (ii), (iii) and (iv) are used in quantities such that the molar ratio of si - atoms in the compounds of the formulae (ii) and (iii) to oh - groups in the compounds of the formula (iv) of 0,01 to 1 to 1000 to 1, the reaction at a temperature of greater than 70 to 175°C. is carried out, and the resulting reaction mixture does not is treated with an acidic compound.
