- EP 1 988 13 discloses a molding composition based on a 10T / 6T copolyamide with:
- polyamides having a high melting point and greater than 270 ° C. are used.
- the examples mentioned and Figure 1 teach us that the melting temperature of these compositions is at least about 280 ° C.
- WO 201 1/003973 describes compositions comprising from 50 to 95 mol% of a linear aliphatic diamine-based unit containing from 9 to 12 carbon atoms and terephthalic acid and from 5 to 50% of a unit-forming unit. terephthalic acid to a mixture of 2,2,4 and 2,4,4 trimethylhexanediamine.
