    Abstract: The invention relates to a method for producing polymer mixtures by reacting at least one amino nitrile with water in the presence of thermoplastic polymers and optional additional monomers which form polyamide. The inventive method comprises the following steps: (1) reacting at least one amino nitrile with water at a temperature ranging from 90 to 400 degrees C and under a pressure ranging from 0.1 to 35 x 106 Pa, whereby a reaction is obtained; (2) additional reaction of the reaction mixture ranging from 150 to 400 degrees C and under a pressure which is lower than the pressure in step (1), whereby the temperature and pressure are selected in such a way that a first gas phase and a first liquid or a first solid phase of a mixture comprised of the first solid and first liquid phases are obtained, and the first gas phase is separated off from the first liquid or the first solid phase or from the mixture comprised of the first liquid and the first solid phases; and (3) mixing the first liquid or the first solid phase or the mixture comprised of the first liquid and first solid phases with a gaseous or liquid phase which contains water and which can contain thermoplastic polymers and optional additional monomers which form polyamide. Said mixing occurs at a temperature ranging from 150 to 370 degrees C and under a pressure ranging from 0.1 to 30 x 106 Pa, whereby the polymer mixture is obtained and whereby the thermoplastic polymers and optional additional monomers which form polyamide are added in one or more of the steps. 6 claims
