A molding composition, comprising: I. from 97 to 80 parts by weight of a polyetheramide based on a linear aliphatic diamine having from 6 to 14 carbon atoms, a linear aliphatic or aromatic dicarboxylic acid having from 6 to 14 carbon atoms, and a polyetherdiamine which has at least 3 carbon atoms per ether oxygen and has primary amino groups at the chain ends, and II. from 3 to 20 parts by weight of a rubber containing functional groups, each per 100 parts by weight of a total of components I. and II., is suitable for extrusion of moldings such as flexible pipes. The molding composition is resistant to hydrolysis and heat and has high melt viscosity and the resulting moldings, without an external plasticizer, have long-lasting flexibility and good low-temperature impact strength. |
