摘要：
本发明涉及一种透明无定形聚酰胺，它通过如下物质缩合获得：至少一种二胺，选自芳香族、芳脂族和环脂族二胺；十四烷二酸或包括至少50mol％十四烷二酸与至少一种选自脂族、芳香族和环脂族二酸的混合物。本发明还涉及一种组合物，包括1至100重量％的前述的聚酰胺和99至0重量％的半结晶聚酰胺。本发明还涉及由本发明组合物组成的制品，如板、薄膜、片材、管、型材，或通过注塑获得的制品。本发明还涉及由本发明的组合物制成的透明保护层覆盖的制品。
摘要（英）：

The present invention relates to a transparent amorphous polyamide which results from the condensation of at least one diamine chosen from aromatic, arylaliphatic and cycloaliphatic diamines, of tetradecanedioic acid or of a mixture comprising at least 50 mol % of tetradecanedioic acid and at least one diacid chosen from aliphatic, aromatic and cycloaliphatic dicarboxylic acids. The invention also relates to a composition comprising, by weight, 1 to 100% of the preceding polyamide and 99 to 0% of a semicrystalline polyamide. The invention also relates to the objects composed of the composition of the invention, such as panels, films, sheets, pipes, profiles or objects obtained by injection moulding. The invention also relates to objects covered with a transparent protective layer composedof the composition of the invention.
