Abstract
The present invention relates to a polymer film (P) contacting at least one copolyamide. The copolyamide is prepared by polymerizing a first monomer mixture (M1), containing at least one C-Cdicarboxylic acid and at least one C-Cdiamine, and a second monomer mixture (M2) containing at least one C-Cdimer acid and at least one C-Cdiamine. The present invention further relates to a process for producing the polymer film (P) and to the use of the polymer film (P) for high-temperature applications.
