Patent ID: 8362185

Claim:
A polyammonium/polysiloxane copolymer; comprising repeat units of the formula (I): wherein groups R are independently organic groups which contain at least one selected from the group consisting of quaternary ammonium groups and amine oxide groups, wherein V is selected from a plurality of groups V 1 and a plurality of groups V 2 , wherein the plurality of groups V 1 may be the same or different, and the plurality of groups V 2 may be the same or different, in which V 2 is selected from divalent and trivalent, straight-chain, cyclic and branched, saturated, unsaturated and aromatic hydrocarbons including at least one Z 2 group of the formula wherein groups R 1 may be the same or different and are selected from the group consisting of C 1 -C 22 alkyl, fluoro (C 1 -C 10 ) alkyl, and C 6 -C 10 aryl, and wherein n 1 =20 to 1000, wherein V 2 includes up to 1000 carbon atoms exclusive of the Z 2 group, and wherein V 2 may optionally contain one or more groups selected from —OH, —O—, —NR 2 —, —N + R 2 2 —, in which R 2 is hydrogen, a monovalent, straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical which has up to 100 carbon atoms and may contain one or more groups selected from —O—, —NH—, —C(O)— and —C(S)—, and which may optionally be substituted by one or more substituents selected from the group consisting of a hydroxyl group, an optionally substituted heterocyclic group containing one or more nitrogen atoms, amino, alkylamino, dialkylamino, polyether radicals and polyetherester radicals, where, when a plurality of —NR 2 -groups is present, they may be the same or different, —C(O)—, —C(S)— and wherein V 1 is selected from divalent and trivalent, straight-chain, cyclic and branched, saturated, unsaturated and aromatic hydrocarbon radicals which have up to 1000 carbon atoms and may optionally contain one or more groups selected from —OH, —O—, —NR 2 —, —N + R 2 2 —, in which R 2 is as defined above, and where the R 2 groups in the V 1 and V 2 groups may be the same 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, where the R 1 groups in the V 1 and V 2 groups may the same or different, n 2 =0 to 19, wherein at least one Z 1 or Z 2 group is present, and wherein acid anions neutralize the ammonium groups.
