Abstract
The present invention relates to a copolyamide (CoPA) produced by polymerizing a first monomer mixture (M1) and a second monomer mixture (M2), where the second monomer mixture (M2) comprises 1,5-diamino-3-oxapentane. The present invention further relates to polymer film comprising the at least one copolyamide (CoPA) and to a process for producing the polymer film.
Claims17
A copolyamide produced by polymerizing the following components:
- (A) 39-95% by weight of at least one first monomer mixture (M1) comprising the components
- (A1) at least one C4-C12 dicarboxylic acid, and
- (A2) at least one first C4-C12 diamine
- (B) 5-61% by weight of a second monomer mixture (M2) comprising the following components:
- (B1) at least one C4-C12 dicarboxylic acid and
- (B2) at least one second diamine,
- where component (B2) comprises 1,5-diamino-3-oxapentane and where the percentages by weight of components (A) and (B) are in each case based on the sum total of the percentages by weight of components (A) and (B).
