Abstract (en)
[origin: WO2023041367A1] The invention relates to a copolyamide (CoPA) produced by polymerizing a lactam (A) and a monomer mixture (M), the monomer mixture (M) containing 1,5-diamino-3-oxapentane. The invention further relates to a polymer film containing the at least one copolyamide (CoPA), a process for producing the polymer film, and the use of the polymer film (P) as a packaging film.
