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 C4-C12 dicarboxylic acid and at least one C4-C12 diamine, and a second monomer mixture (M2) containing at least one C32-C40 dimer acid and at least one C4-C12 diamine. 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.
Claims15
A polymer film (P), comprising at least one copolyamide, which is prepared by polymerizing the following components:
- (A) 15% to 95% by weight of a first monomer mixture (M1) comprising the following components:
- (A1) at least one C4-C12 dicarboxylic acid and
- (A2) at least one first C4-C12 diamine,
- (B) 5% to 85% by weight of a second monomer mixture (M2) comprising the following components:
- (B1) at least one C32-C40 dimer acid and
- (B2) at least one second C4-C12 diamine,
- where the percentages by weight of the components (A) and (B) are based on a total weight of the components (A) and (B).
