Abstract (en)
[origin: WO2017198949A1] The invention concerns a composition comprising: (A) an amorphous or quasi-amorphous copolymer with polyamide blocks and polyether blocks, the polyamide blocks comprising cycloaliphatic units; (B) a semi-crystalline polymer or copolymer comprising amide units; (C) another polymer or copolymer comprising amide units; and (D) a polymer having several layers, comprising at least one layer (D1) and one layer (D2). This composition has advantageous transparency and impact resistance properties, in particular for the production of sport items.
