Abstract

Method for the prepn. of organopolysiloxanes contg. at least one unit of formula (I), comprises: (i) reacting organosilicon cpds. (1) contg. at least one hydroxyl gp.bonded to a Si atom, with at least one silane (2) of formula (II) and/or partially hydrolysed derivs. thereof, in the presence of a fluoride salt (3); and (ii) once the reaction has finished, opt. adding a component (4) that can bind fluoride ions. (R<1>O)3-mRmSiO1/2 (I) (R<1>O)4-mSiRm (II) (R = H or monovalent, opt. substd. hydrocarbon; R<1> = 1-8C monovalent opt. substd. hydrocarbon; and m = 0-2).
