Beschreibung
Zusammenfassung:	(Co)polymers (c1) comprises structural amide units; at least 10 mol.% of structural diamide units; and polyether units (E1) having an average molecular weight of 200 - 6000 g/mol. (Co)polymers (c1) comprises structural amide units of formula -[W(COZ)CONH]- (I); at least 10 mol.% of structural diamide units of general formula -[W(CONR3R4)CONH]- (Ia); and polyether units (E1) having an average molecular weight of 200 - 6000 g/mol. [structures (i) - (xii), US2005058619A1-001] W : a trivalent radical from group of formulae (i) - (xiv); R1aH or COZ; Z : radicals -OH, -O->M+> or -N-R1R2; R1 and R2alkenyl radicals, aralkyl radicals or (cyclo)alkyl radicals (all optionally substituted, and are optionally interrupted by O, N, Si, amido, carbonate, urethane, urea, allophanate, biuret and/or isocyanurate groups) or H; M+>H+>, alkali metal ion, NH4 ion or a primary, secondary, tertiary or quaternary aliphatic ammonium radical; R3a 1-60C hydrocarbon radical; R4H or R3. * indicates the orientation for the incorporation of the radical W into the formula I. An independent claim is included for the preparation of (c1).
