Abstract
The invention relates to a novel grade of copolymides of tetramethyleneadipamide (nylon 4.6) and tetramethyleneterephthalamide (nylon 4.T) containing a mole fraction nylon 4.T of 0.1 to 0.6 and having such a degree of orientation that the melting temperature shows little dependence on the composition of the copolyamide and remains relatively low and which copolyamides have good mechanical properties.
