Linear polyamino and/or polyammonium polysiloxane copolymers I

Linear polyamino- and/or polyammonium-polysiloxane copolymers containing the repeating unit

• -[Q-V—]— (I)
• in which Q is selected from the group consisting of
• —NR—,
• —N+R2—,
• 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 V1 and at least one group V2
• in which
• V2 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 Z2, defined below) and containing, if desired, one or more groups selected from
• —O—, —CONH—,
• —CONR2—, in which R2 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 —CONR2—, they may be identical or different,
• —C(O)— and —C(S)—, and
• the radical V2 may if desired by substituted by one or more hydroxyl groups, and
• the radical V2 contains at least one group -Z2- of the formula
• in which
• R1 can be identical or different and is selected from the group consisting of C1 to C22 alkyl, fluoro(C1-C10)alkyl and C6-C10 aryl, and n1=20 to 1000,
• V1 is selected from dihydric or trihydric, 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—,
• —CONR2—, in which R2 is as defined above, it being possible for the groups R2 in the groups V1 and V2 to be identical or different,
• —C(O)—, —C(S)— and -Z1 -, in which -Z1- is a group of the formula
• in which
• R1 is as defined above, it being possible for the groups R1 in the groups V1 and V2 to be identical or different, and
• n2=0 to 19,
• and the radical V1 may if desired be substituted by one or more hydroxyl groups,
• with the provisos that the trivalent radicals Q and the trivalent radicals V1 or V2 serve exclusively for saturating one another within the linear main chain of the polysiloxane copolymers,
• and that in the copolymer the molar ratio
• V2/V1<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.
