Acidic interchange of siloxane bonds with silicon-bonded alkoxy and acyloxy bonds

Claim 1

THE PROCESS OF REACTING AT A TEMPERATURE OF 20* TO 150*C., IN THE PRESENCE OF A CATALYST SELECTED FROM THE GROUP CONSISTING OF STRONG ACIDS HAVING DISSOCIATION CONSTANTS FOR THEIR MOST ACIDIC HYDROGEN ATOM OF NO LESS THAN 0.05 IN A 0.1 N WATER SOLUTION AT 25*C., AND ACIDIC SALTS THEREOF WHICH HAVE A PH OF LESS THAN 7 WHEN TESTED AS A 0.1 N WATER SOLUTION AT 25*C., A SILICONE REACTANT COMPRISING AT LEAST ONE ORGANOSILICON COMPOUND, SAID SILICONE REACTANT CONTAINING (1) SILOXANE BONDS AND (2) BONDS SELECTED FROM THE GROUP CONSISTING OF SILICON-BONDED LOWER ALKOXY AND SILICON-BONDED LOWER ALKOXY, THE OTHER BONDS IN SAID SILICON REACTANT CONSISTING ESSENTIALLY OF THOSE SELECTED FROM THE GROUP CONSISTING OF $SIH, SI-MONOVALENT HYDROCARBON, SI-MONOVALENT HALOHYDROCARBON, SIDIVALENT HYDROCARBON-SI, AND SI-DIVALENT HALOHYDROCARBON-SI, WHEREBY AN EXCHANGE REACTION OCCURS BETWEEN SAID BONDS (1) AND (2).
