Abstract

Thermoplastic molding compositions that contain PA0 (A) 10 to 90 parts by weight of polyamide 12, and 90 to 10 parts by weight of polyamide 10,12 and/or polyamide 12,12; and PA0 (B) 0 to 25 wt. % of a plasticizer, exhibit improved low temperature impact strength. The molding compositions may be used for the production of molded objects, especially tubes.
