摘要

Thermoplastic molding compositions having improved flexibility and cold impact strength, comprising a mixture of: I. at least one polyamide from omega-aminocarboxylic acids or lactams having at least 10 carbon atoms; and II. at least one polyether ester amide with units of the starting components randomly distributed in the polymer chain produced from: (a) omega-aminocarboxylic acid or lactams having at least 10 carbon atoms, (b) alpha, omega-dihydroxy(polytetrahydrofuran) having a molecular weight of between 160 and 3,000 and (c) a dicarboxylic acid. The mixture contains about 95 to 20 percent by weight of component I and about 5 to 80 percent by weight of component II.
