AMIDGRUPPENHALTIGE POLYAMINE

Water-soluble amines which are not self-crosslinking and are obtainable by reacting (A) one or more water-soluble or water-dispersable amines containing amide groups, prepared by condensation of (a) 1 mol of dicarboxylic acid or functional derivatives thereof, (b) 0 to 30 mols of aminocarboxylic aci...

Zusammenfassung:	Water-soluble amines which are not self-crosslinking and are obtainable by reacting (A) one or more water-soluble or water-dispersable amines containing amide groups, prepared by condensation of (a) 1 mol of dicarboxylic acid or functional derivatives thereof, (b) 0 to 30 mols of aminocarboxylic acids containing at least three C atoms, or lactams thereof, and (c) 1.4 to 30 mols of polyalkylenepolyamines of the general formula in which R denotes H or CH3, y is in each case the same or different and denotes the number 0 or 1 and x denotes a number from 4 to 15, and (B) compounds which are polyfunctional towards amino groups, are suitable as agents for increasing the retention of fibres, fillers and pigments, for accelerating drainage during the production of paper and for working up effluents from paper machines.
