ABSTRACT:
Organosiloxane fluids containing polyfunctional silicon atoms are made by reacting a mixture of chlorosilanes containing a silane or disilane having at least 3 chlorine atoms with methanol in contact with certain quaternary ammonium halide catalysts. For example a fluid methylpolysiloxane was obtained by reacting a mixture of 30 weight percent methyltrichlorosilane and 70 weight percent dimethyldichlorosilane with methanol in contact with methyl pyridinium chloride.
