Abstract

Linear or branched organic silicone polymers having average mol. masses between 1000 and 10 million and which may carry various alkyl, aryl, aralkyl and/or alkenyl substds. and may or may not have reactive end gps. are prepd. by polycondensation and/or equilibration reactions between siloxane oligomers having silanol end gps. and opt. alkyl-chloro-silan and/or polysiloxane oligomers in the presence of 10-15 ppm oxo-halogen-acid or oxo-halogen-acid derivs. as catalysts and in the presence of organic-carboxylic acids or organic carboxylic-acid derivs. and/or alcohol or alcohol derivs. at 20-200 deg.C The reaction mixt. is subsequently neutralised with an inorganic or organic base.
