Patent ID: 7939616

Claim:
A mixture, comprising: catenary, branched and/or cyclic siloxanes of the general formula I R x SiO (4-x)/2 (I) wherein x is 1, 2 or 3, the substituents R are as follows, with the proviso that at least one group (i) is present, (i) 1-aminomethyl, N-(2-aminoethyl)-1-aminomethyl, N,N-di(2-aminoethyl)-1-aminomethyl, N—[N′-(2-aminoethyl)-2-aminoethyl)]-1-aminomethyl, N-methyl-1-aminomethyl, N-(n-butyl)-1-aminomethyl, N-cyclohexyl-1-amino-methyl, ureidomethyl or N-phenyl-1-aminomethyl groups, (ii) hydroxyl, methoxy, ethoxy, 2-methoxyethoxy, isopropoxy, n-propoxy, isobutoxy and/or n-butoxy groups, and (iii) optionally, alkyl, alkenyl, isoalkyl, cycloalkyl or fluoroalkyl groups having 1 to 18 carbon atoms or aryl groups having 6 to 12 carbon atoms, with the proviso that not more than one organofunctional group (i) is attached per silicon atom, the quotient of the molar ratio of the moiety (ii) to silicon is from 1 to 2, and the degree of oligomerization for compounds of the general formula I is in the range from 2 to 50.
