Claim:
Linear polyamino-polysiloxane and/or polyammonium-polysiloxane copolymers containing the repeating unit -[Q-V—]— (I) in which Q is selected from the group consisting of —NR—, —N + R 2 —, a saturated or unsaturated diamino-functional heterocycle of the formulae an aromatic diaminofunctional heterocycle of the formula a trivalent radical of the formula: a trivalent radical of the formula in which R in each case is hydrogen or a monovalent organic radical, Q not bonding to a carbonyl carbon atom, V represents at least one group V 1 or at least one group V 2 in which V 2 is selected from divalent or trivalent, straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radicals having up to 1000 carbon atoms (not including the carbon atoms of the polysiloxane radical Z 2 , defined below) and containing, if desired, one or more groups selected from —O—, —CONH—, —CONR 2 —, in which R 2 is hydrogen, a monovalent, straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 100 carbon atoms, which may contain one or more groups selected from —O—, —NH—, —C(O)— and —C(S)—, and which may if desired be substituted by one or more substituents selected from the group consisting of a hydroxyl group, an unsubstituted or substituted heterocyclic group preferably containing one or more nitrogen atoms, amino, alkylamino, dialkylamino, ammonium, polyether radicals and polyetherester radicals, and, if there are two or more groups —CONR 2 —, they may be identical or different, —C(O)— and —C(S)—, and the radical V 2 may if desired by substituted by one or more hydroxyl groups, and the radical V 2 contains at least one group -Z 2 - of the formula in which R 1 can be identical or different and is selected from the group consisting of C 1 to C 22 alkyl, fluoro(C 1 -C 10 )alkyl and C 6 -C 10 aryl, and n 1 =20 to 1000, V 1 is selected from divalent or trivalent, straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radicals having up to 1000 carbon atoms, which if desired may contain one or more groups selected from —O—, —CONH—, —CONR 2 —, in which R 2 is as defined above, it being possible for the groups R 2 in the groups V 1 and V 2 to be identical or different, —C(O)—, —C(S)— and -Z 1 -, in which -Z 1 - is a group of the formula in which R 1 is as defined above, it being possible for the groups R 1 in the groups V 1 and V 2 to be identical or different, and n 2 =0 to 19, and the radical V 1 may if desired be substituted by one or more hydroxyl groups, with the provisos that the trivalent radicals Q and the trivalent radicals V 1 or V 2 serve exclusively for saturating one another within the linear main chain of the polysiloxane copolymers, and that in the copolymer the molar ratio V 2 /V 1 <1:3, and in which the positive charges resulting from the ammonium groups are neutralized by organic or inorganic acid anions, and the acid addition salts thereof.
