摘要:
A SILICONE FLUID MIXTURE USEFUL AS A HYDRAULIC FLUID AND, MORE PARTICULARLY, USEFUL AS A BRAKE FLUID COMPRISING (A) 1 TO 80% BY WEIGHT OF THE TOTAL FLUID MIXTURE OF A HYDROCARBONOXY-CONTAINING POLYMER FLUID AND 20 TO 99% BY WEIGHT OF THE TOTAL FLUID OF A LINEAR POLYMER SILICONE FLUID OF THE FORMULA, (R10-)N-SI-O((4-N)/2) WHERE N VARIES FROM 2.0 TO 3.0, R10 IS SELCECTED FROM MONOVALENT HYDROCARBON RADICALS, HALOGENATED MONOVALENT HYDROCARBON RADICALS AND LOWER CYANOALKYL RADICALS AND THE VISCOSITY OF THE LINEAR FLUID VARIES FROM 20 TO 500 CENTISTOKES AT 25*C. THERE MAY BE ADDED TO THE ABOVE SILICONE FLUID MIXTURE VARIOUS TYPE SOF ANTI-OXIDANT AND CORROSION INHIBITION ADDITIVES, AS WELL AS VARIOUS TYPES OF RUBBER SWELL ADDITIVES.

COMPOSITIONS SUBSTITUTED WITH IODINE, WITH EITHER BROMINE OR CHLORINE, AND WITH EITHER ALKOXY, ACYLOXY, OR HYDROXY GROUPS ARE PREPARED BY ADDING A MIXTURE OF IODINE AND EITHER BROMINE OR CHLORINE OR IBR OR ICL TO ALPHA-OLEFINS IN THE PRESENCE OF ALCOHOLS, CARBOXYLIC ACIDS, OR WATER. LUBRICATING COMPOSITIONS USEFUL FOR LUBRICATING HIGH TEMPERATURE ALLOYS ARE PREPARED BY ADDING SUCH COMPOUNDS TO OILS OF LUBRICATING VISCOSITY.

摘要:
Compositions substituted with iodine, with either bromine or chlorine, and with either alkoxy, acyloxy, or hydroxy groups are prepared by adding a mixture of iodine and either bromine or chlorine or IBr or ICI to alpha-olefins in the presence of alcohols, carboxylic acids, or water. Lubricating compositions useful for lubricating high temperature alloys are prepared by adding such compounds to oils of lubricating viscosity.
