摘要:
The invention provides a process for preparing branched SiH-functional siloxanes by converting a mixture of one or more low molecular weight SiH-functional siloxanes, one or more low molecular weight SiH-free siloxanes and one or more trialkoxysilanes with addition of water and in the presence of at least one Brønsted-acidic catalyst, which is characterized in that the reaction is performed in one process step.
