    Abstract: The process for producing polymer blends by reacting at least one aminonitrile with water in the presence of thermoplastic polymers and optionally further polyamide-forming monomers comprises the following steps:(1) reacting at least one aminonitrile with water at a temperature from 90 to 400° C. and a pressure from 0.1 to 35x106 Pa to obtain a reaction mixture,(2) further reacting the reaction mixture at a temperature from 150 to 400° C. and a pressure which is lower than the pressure in step 1, the temperature and pressure being selected so as to obtain a first gas phase and a first liquid or a first solid phase or a mixture of first solid and first liquid phase and the first gas phase is separated from the first liquid or the first solid phase or the mixture of first liquid and first solid phase, and(3) admixing the first liquid or the first solid phase or the mixture of first liquid and first solid phase with a gaseous or liquid phase comprising water, which phase may contain thermoplastic polymers and optionally further polyamide-forming monomers, at a temperature from 150 to 370° C. and a pressure from 0.1 to 30x106 Pa to obtain the polymer blend,wherein in one or more of the steps the thermoplastic polymers and optionally further polyamide-forming monomers are added.

    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 ~C and under a pressure ranging from 0.1 to 35 x 106 Pa, whereby a reaction mixture is obtained; (2) additional reaction of the reaction mixture at a temperature ranging from 150 to 400 ~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 or 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 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 ~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.
