More Information
Summary:The invention relates to a composition comprising:(A) an amorphous or quasi-amorphous copolymer containing polyamide blocks and containing polyether blocks, the polyamide blocks comprising cycloaliphatic units;(B) a semicrystalline polymer or copolymer comprising amide units;(C) another polymer or copolymer comprising amide units; and(D) a multilayer polymer comprising at least a layer (D1) and a layer (D2).This composition has advantageous properties of transparency and impact strength, especially for the manufacture of sports articles.
