    摘要: The invention comprises siloxanes of the formula wherein X is a halogen atom or an alkoxy or hydroxyl radical and n is zero or an integer. The halogen-terminated siloxanes can be made by halogenating the corresponding H-containing siloxanes (which can be made by co-hydrolysis and condensation of [(CH3)3SiO]2Si(OCH3)2 and [(CH3)3SiO]2H.SiOCH3), and the hydroxylate and alkoxylated siloxanes can be obtained from the halogenated siloxanes by hydrolysis and alcoholysis respectively. Examples describe the preparation of {[CH3)3SiO]2XSi}2O, in which X is (1) Cl, (2, 3) -OH and (4) -OCH3, -OC2H5, -OCH(CH3)2 and -OC4H9; Example (5) describes the preparation of siloxanes of the above general formula in which n is 1, 2, 3, 4, 5, 10, 15, 25, 50, 100 and 1500, and X is Cl, -OH, or alkoxy as specified in Example (4). Uses.-Fluid springs, hydraulic fluids and lubricants or as protective coatings for metals, wood and glass. The H-containing siloxanes can be made as follows:

Siloxanes (1) can be made, e.g. by cohydrolysing [(CH3)3SiO]2Si(OCH3)2 and H(CH3)2SiOCH3 or (C6H5)(CH3)HSiOCH3 and then co-condensing the hydrolysates, or preferably by reacting [(CH3)3SiO]4Si with (C6H5)(CH3)HSiCl or [(CH3)2HSi]2O in the presence of a catalyst, e.g. FeCl3 or a sulphonic acid ion-exchange resin. Siloxanes (2) can be made, e.g. by cohydrolysing (CH3)3SiOCH3 and [H(CH3)2SiO]2Si(OCH3)2 or [(C6H5)(CH3)HSiO]2 Si(OCH3)2 and then co-condensing the hydrolysates. These H-containing siloxanes may be chlorinated to yield the corresponding chlorine-containing siloxanes which in turn can be converted to the hydroxy- or alkoxy-containing siloxanes by hydrolysis or alcoholysis. Examples are given. Uses.-as "fluid springs," hydraulic fluids and lubricants.
