1. A process for preparing a composition containing quaternary amino-functional organosilicon compounds,
characterized in that it comprises reacting
as component A (i) at least one haloalkyl-functional alkoxysilane of the general formula I
(R10)3-x-y(R2)xSi[(R3)nCH2Hal]1+y (I), where the R1 groups are the same or different and R1 represents a hydrogen, a linear, branched, or cyclic alkyl group having 1 to 8 carbon atoms, an aryl, arylalkyl or acyl group, the R2 groups are the same or different and R2 represents a linear, branched or cyclic alkyl group having 1 to 8 carbon atoms, or an aryl, arylalkyl or acyl group, the R3 groups are the same or different and R2 signifies a linear, branched or cyclic alkylene group having 1 to 18 carbon atoms, n is equal to 0 or 1 and Hal represents chlorine or bromine, and x is equal to 0, 1 or 2, y is equal to 0, 1 or 2 and (x+y) is equal to 0, 1 or 2, or (ii) a hydrolysis or condensation product of at least one alkoxysilane of the aforementioned general formula I or (iii) a mixture of at least one alkoxysilane of the aforementioned general formula I and a hydrolysis and/or condensation product of at least one alkoxysilane of the aforementioned general formula I
with a tertiary amine of the general formula II as component B,
N(R4)3 (II), where the R4 groups are the same or different and R4 represents a group (R10)3-x-y(R2)xSi[(R3)nCH2—]1+y, where R1, R2, R3, n, x, y and (x+y) likewise have the aforementioned meaning, or represents a linear, branched or cyclic alkyl group having 1 to 30 carbon atoms which may additionally be substituted, where optionally two R4 groups are in turn linked together and combine with the nitrogen of the tertiary amine to form a cycle,
in the presence of a defined amount of water, andremoving the resulting hydrolysis alcohol at least partially from the system. |
