Patent ID: 8450512

Claim:
A method for producing an aminosiloxane compound the general formula: wherein R 1 and R 2 are alkyl radicals each having 1 to 18 carbon atoms, an alkyl-aryl or aryl radicals; and wherein R 3 is a an alkyl radical having 1 to 18 carbon atoms, an alkyl-aryl radical, an aryl radical, or trimethylsilyl; and wherein n is an integer equal to 0, 1 or 2, the method comprising the step of: reacting hexamethylsilazane with an aminosiloxane compound of the following general formula: wherein R 1 and R 2 are alkyl radicals having 1 to 18 carbon atoms, an alkyl-aryl or aryl radicals; wherein R 3 is an alkyl radical having 1 to 18 carbon units, an alkyl-aryl radical, an aryl radical or hydrogen and; wherein n is an integer equal to 0, 1 or 2, to produce an admixture comprising: a) the compound of general formula I; and b) Me 3 SiOR 1 , wherein R 1 is an alkyl radical having 1 to 18 carbon atoms, an alkyl-aryl or an aryl radical.
