Abstract
Crosslinked aminosiloxanes obtainable by reaction of identical or different aminosiloxanes with identical or different epoxide components which are water-soluble hydrocarbons, the hydrocarbons comprising oxygen as well as carbon, and optionally further elements selected from nitrogen, sulphur and phosphorus, the hydrocarbon having on average more than one terminal epoxy group, the epoxy group being a carbooxirane radical, and, further, not more than 50% of all the amino groups having undergone reaction with an epoxide group.
Claims16
A crosslinked aminosiloxane obtained by reaction of identical or different amine-substituted siloxanes with identical or different epoxide components which are water-soluble hydrocarbons, the hydrocarbons comprising oxygen and carbon, the hydrocarbon having on average more than one terminal epoxy group, the epoxy group being a carbooxirane radical, and, further, not more than 50% of all the amino groups having undergone reaction with an epoxide group
- wherein the epoxide components are epoxy-substituted polyethers of formula (II)
- R3—X-M1h-M2j-M3k-M4l-M5m-R3 (II)
- h=greater than 0 to 50;
- j=0 to 10;
- k=0 to 10;
- l=greater than 1 to 10;
- m=0 to 10;
- where the sum of the indices h, j, k, l+m is at least 3,
- X=oxygen,
- R3=independently at each occurrence hydrogen, a hydrocarbon having 1 to 8 carbon atoms, and/or the gycidyl radical
- where in M3, the radicals X1 to X4 independently of one another are hydrogen or linear, cyclic or branched, aliphatic or aromatic, saturated or unsaturated hydrocarbon radicals having 1 up to 50 C atoms, wherein X1 to X4 are not selected such that M3 is the same as M1 or M2,
- where R4 in M4 independently at each occurrence is a hydrocarbon radical having 2 to 20 carbons, and may be interrupted by heteroatoms, M4 is a glycidyl ether=
- where R5 in M5 independently at each occurrence is not present or is a divalent hydrocarbon having 1 to 10 carbon atoms.
