ABSTRACT:
Process for the production of condensation products or organosilicon compounds having at least one silicon-bonded hydroxyl group. The process comprises contacting the organosilicon compound with a quaternary ammonium borate, -phosphate, -carbonate or -silicate. May be employed for example for the polymerisation of .alpha., w silanol-terminated polydiorganosiloxanes and for the production of organosiloxanes having organofunctional e.g. aminoalkyl groups.
