Patent ID: 8080625

Claim:
Organopolysiloxanes containing quaternary ammonium groups, of the formula: A d R 3-d SiO(SiR 2 O) o (SiRAO) p SiR 3-d A d (V) where A is either E or Q, d is 0, o is 0 or an integer from 1 to 3000, and p is an integer from 2 to 100, where R is identical or different and is a monovalent, optionally halogenated hydrocarbyl radical having 1 to 18 carbon atoms, E is a monovalent SiC-bonded organic radical having 3 to 18 carbon atoms which contains an epoxy group, Q is a monovalent SiC-bonded organic radical in which a quaternary ammonium group is bonded to a silicon atom via a ring-opened epoxy group, with the proviso that the organopolysiloxanes each comprise at least one Q group and at least one E group and the Q/E ratio is on average in the range from 0.2 to 100.
