FIELD: chemistry.SUBSTANCE: invention relates to polyamide-elastomer mixtures for making moulded articles. The polyamide-elastomer mixture contains components in the following ratios, wt %: a) 30 to 95 of at least one partially crystalline polyamide having a solution viscosity greater than or equal to 1.75 (measured in m-cresol solution, 0.5 wt %, 20°C.), b) 5 to 50 of at least one elastomer produced by emulsion polymerisation of at least one conjugated diene, at least one ?,?-unsaturated nitrile and, optionally, one or more additional copolymerisable monomers and subsequent spray drying of the latex obtained during emulsion polymerisation, c) optionally, 0 to 20 of one or more polyamides having a solution viscosity of less than 1.75 (measured in m-cresol solution, 0.5 wt %, 20°C.), relative to the total amount of components (a) to (c), and relative to 100 parts by weight of components (a) to (c), from 0 to 100 parts by weight of one or more additives. The disclosed polyamide-elastomer mixtures can be processed into moulded articles which are used, for example, in the motor car industry, particularly as channel conducting media.EFFECT: good flexibility of polyamide-based materials and improved resistance to hydrolysis and oil swell.33 cl, 4 dwg, 2 tbl, 1 ex |
