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 composed of the composition of the invention.
