- Claim: 1. Polyurethane/polyorganosiloxane and/or polyurea-polyorganosiloxane compounds and salts thereof that contain at least one structural element of formula [II] [chemical expression included] and R i is a structural element of formula [III] [chemical expression included] in which V has the structure [V]: [chemical expression included] in which n=0 to 10, and X is derived from aromatic, cycloaliphatic or aliphatic, at least divalent, linear or branched mono- or polyisocyanates and their mixtures of isomers and/or mixtures of different diisocyanates having up to 15 carbon atoms that were subjected to a carbodiimidation reaction, wherein said reaction yields a compound of formula [XII]: [chemical expression included] wherein —V— is as defined above, and x≥2; P 1 is derived from polyols or polyamines adhering to formula (XIII) where P 1 is a polymer moiety selected from the group consisting of a polycarbonate, polyester, polyether, polyacrylate, polyolefin, polydimethylsiloxane, polylactone, polyamides, polyurea, polyurethane, copolymers thereof, and mixtures of such polymers, terminated with hydroxyl- or amine groups: [chemical expression included] wherein g≥1, and Y=—NR A — or —O—, and RA represents hydrogen or a linear, branched, cyclic, saturated, unsaturated or aromatic hydrocarbyl radical with up to 20 carbon atoms, which may additionally contain several groups selected from —O—, —C(O)—, —NH—, tertiary amines, or quaternary ammonium compounds; P 2 is derived from an α,ω-primary or secondary amino- or hydroxyalkyl- or hydroxypolyetheralkyl-functionalized polyorganosiloxane having the structure [chemical expression included] in which s=2 to 500 and s′=1 to 3, D and D′ are primary or secondary hydroxy- or aminoalkyl- or hydroxypolyether-terminated organic radicals having up to 200 carbon atoms, which is capable of undergoing a chemical polyaddition reaction with [XII], D and D′ are additionally the same or different, and R x is a linear, branched, cyclic, saturated, unsaturated, aromatic, substituted or unsubstituted hydrocarbyl radical having up to 20 carbon atoms, which may additionally bear amino or quaternary ammonium compounds or hydroxyalkyl or hydroxypolyetheralkyl groups, whereby P may provide a comb-like structure, P 2 is selected independently of P 1 ; P 3 is a linear, branched, cyclic, saturated, unsaturated, aromatic, substituted, or unsubstituted group with up to 20 carbon atoms, which is converted to its salts by a protonatable or deprotonatable group -J-, to enable the polymer to achieve water solubility, emulsifiability and/or dispersibility, where, x, y, and z are all integers ≥1; and a chain extender —U— selected from aliphatic, monovalent, divalent or polyvalent, linear or branched polyols or polyamines with up to 15 carbon atoms, or from primary or secondary amino- or hydroxy-terminated polyethers with a molecular weight of up to 1000 g/mol.
