Examples of organosiloxanes given include those composed exclusively of the said units, and copolymers composed of these siloxane units and siloxane units according to the general formula R.sub.b (SiO.sub.4-b)/2 in which each R is a substituted or unsubstituted hydrocarbon group of up to 10 carbon atoms, and b has the value 0. 1, 2 or 3, for example those according to the average general formula
