ABSTRACT:
The invention relates to a polymer mixture of partially crystalline aliphatic polyamides and partially aromatic polyamides, the proportion of aliphatic polyamides being more than 50% by weight and the quantitative ratio of the aliphatic carbon atoms to amide bonds in the aliphatic polyamides being in the range of 8:1 to 12:1 and the partially aromatic polyamides, which are present in deficit, having, in addition to hexamethyleneterephthalamide (6T) units, further partially aromatic and/or aliphatic amide units and being predominantly partially crystalline. The invention relates furthermore to the use of polymer mixtures of this type for various application fields, in particular for express couplings or connectors for fuel lines.
