5 à 40% d'un polyamide amorphe (B) qui résulte essentiellement de lancondensation d'au moins une diamine éventuellement cycloaliphatique, d'aunmoins un diacide aromatique et éventuellement d'au moins un monomèrenchoisi parmi :n les acides alpha omega amino carboxyliques, les diacides aliphatiques, les diamines aliphatiques, 0 à 40% d'un polyamide souple (C) choisi parmi les copolymères à blocsnpolyamides et blocs polyether et les copolyamides, 0 à 20% d'un compatibilisant (D) de (A) et (B), (C)+(D) est compris entre 2 et 50% avec la condition que (B)+(C)+(D) n'est pas inférieur à 30%, le complément à 100% d'un polyamide (A) semi cristallin. The invention relates to a transparent composition comprising by weight, the total being 100%: 5 to 40% of an amorphous polyamide (B) which essentially results from the condensation of at least one optionally cycloaliphatic diamine, at least one aromatic diacid and optionally at least one monomer chosen from: alpha omega amino carboxylic acids, aliphatic diacids, aliphatic diamines, 0 to 40% of a flexible polyamide (C) chosen from copolymers with polyamide blocks and polyether blocks and copolyamides, 0 to 20% of a compatibilizer (D) of (A) and (B), (C) + (D) is between 2 and 50% with the condition that (B) + (C) + (D) is not less than 30%, the complement to 100% of a semi-crystalline polyamide (A). n n n The invention also relates to the objects obtained such as plates, films,nsheets, tubes, profiles objects obtained by injection andnespecially films and sheets that are then glued to the skis.n n n The invention also relates to the preceding decorated objects, for example bynsublimation, and covered with a transparent protective layer consistingnof the composition of the invention. |
