Polycarbonate and/or polyurethane polyorganosiloxane compounds

A polycarbonate- and/or polyurethane-polyorganosiloxane compound containing at least one structural element of the formula (1):

• wherein
• Y1 and Y2 are independently chosen from —O—, —S— and —NR2—, wherein
• R2 is hydrogen or a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 40 carbon atoms, which can contain one or more groups chosen from —O—, —C(O)—, —NH— and —NR3—, wherein R3 is a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 40 carbon atoms, which can contain one or more groups chosen from —O—, —C(O)— and —NH—, and
• ST1 and ST2 are independently chosen from divalent to more than divalent, straight-chain, cyclic or branched, saturated, unsaturated or aromatic, substituted or unsubstituted hydrocarbon radicals having up to 1,000 carbon atoms, which can contain one or more groups chosen from —O—, —C(O)—, —NH—, —NR3—,
• and a polyorganosiloxane unit having 2 to 1,000 silicon atoms, wherein
• R5 is a straight-chain, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon radical having up to 100 carbon atoms, which can contain one or more groups chosen from —O—, —C(O)— and —NH—, or R5 is a divalent radical which forms cyclic structures within the radicals ST1 and ST2,
• or one or both of the radicals Y1 adjacent to ST1, with ST1, and/or one or both of the radicals Y2 adjacent to ST2, with ST2, can in each case form a nitrogen-containing heterocyclic radical, and
• wherein if a plurality of radicals ST1 is present, these can be identical or different, and if a plurality of radicals ST2 is present, these can be identical or different,
• ST5 is an optionally substituted, divalent, straight-chain, cyclic or branched, saturated or unsaturated hydrocarbon radical having 1 to 12 carbon atoms,
• ST6 is an optionally substituted, divalent, straight-chain, cyclic or branched, saturated or unsaturated hydrocarbon radical having 1 to 12 carbon atoms,
• with the proviso that ST1 comprises a polyorganosiloxane radical, and wherein
• ST2 represents a radical of the formula
• -ST3-N+(R5)2-ST4-N+(R5)7-ST3-
• wherein
• ST3 is a straight-chain or cyclic or branched, saturated or unsaturated or aromatic, substituted or unsubstituted hydrocarbon radical having to 2 to 100 carbon atoms, which can be substituted by —O—, —C(O)—, —NH—, —NR3—, wherein R3 is as defined above, and
• ST4 is a straight-chain or cyclic or branched, saturated or unsaturated or aromatic, substituted or unsubstituted hydrocarbon radical having to 2 to 100 carbon atoms, which can be substituted by —O—, —C(O)—, —NH—, —NR3— and by a polyorganosiloxane unit having 2 to 200 silicon atoms, wherein R3 is as defined above,
• or acid addition compounds and/or salts thereof of the compound of formula (1).
