Polyamide-elastomer mixtures resistant to hydrolysis, molding parts manufactured from them as well as their use

摘要

Polyamide-elastomer mixture containing a) from 30 to 95% by weight of at least one partially crystalline polyamide with a solution viscosity greater than or equal to 1.75, measured in m-cresol solution, 0.5% by weight at 20 ° C according to DIN EN ISO 307, b) from 5 to 50% by weight of at least one elastomer that is prepared by emulsion polymerization and subsequent spray drying of the latex obtained in emulsion polymerization, c) given the case of 0 to 20% by weight of one or more polyamides with a solution viscosity of less than 1.75, measured in m-cresol solution, 0.5% by weight at 20 ° C according to DIN EN ISO 307, referring the above named indications from% by weight to the total amount of components (a) to (c) and, based on 100 parts by weight of components (a) to (c), from 0 to 100 parts by weight of one or several additives, characterized in that the elastomer b) is prepared by emulsion polymerization of b1) = 55% in weight of at least one conjugated diene, b2) from 5 to 45% by weight of acrylonitrile, b3) in the case of 0 to 5% by weight of one or more radical polymerizable polyfunctional monomers, b4) in the case of 0 to 20% by weight of one or more monomers polymerizable by radicals other than b1) to b3), the indications of% by weight referring to the total amount of components b1) to b4).
