COPOLYMERS HAVING AMIDE UNITS AND ETHER UNITS WITH IMPROVED OPTICAL PROPERTIES

Amide-ether based copolymer (I) is new. The amide is made up of a diamine and a dicarboxylic acid, preferably linear aliphatic acids. The diamine is a cycloaliphatic diamine. The amide units optionally have another polyamide comonomer. (I) has a high degree of transparency of greater than 75% at 560...

Beschreibung
Zusammenfassung:	Amide-ether based copolymer (I) is new. The amide is made up of a diamine and a dicarboxylic acid, preferably linear aliphatic acids. The diamine is a cycloaliphatic diamine. The amide units optionally have another polyamide comonomer. (I) has a high degree of transparency of greater than 75% at 560 nm on a plate with a thickness of 2 mm. (I) is present in an amorphous-/crystalline with an enthalpy of fusion during the second heat of a differential scanning calorimeter of an International Organization for Standardization is 30 J/g. (I) has a glass transition temperature (T g) of 75[deg]C. Independent claims are included for: (1) the preparation of (I); and (2) a shaped article, preferably transparent or translucent article like a fiber, tissue, film, sheet, rod, tube or injected part made up of (I).
