摘要： A method for the preparation of water-soluble, cationic amine polymers by the continuous or batch-wise reaction of a polymer having primary, secondary or tertiary amine functions in its side chain or primary chain as a starting material, wherein the reaction is carried out with an epoxide, a glycidyl ether or a mixture of different epoxides and glycidyl ethers in aqueous solution without additional solvent at a temperature of 30.degree. to 90.degree. C. and at a pH of 8 to 14 within 3 to 30 minutes, the epoxides or glycidyl ethers are added as one batch or in portions, and after adjusting the pH of the aqueous solution of the cationic polymer, which is >13.5 after the reaction with epoxide or glycidyl ether, using a mineral or carboxylic acid, the product solution is obtained without additional work-up steps.
