摘要
Use of a semi-crystalline thermoplastic polyester for producing an aerosol container, said polyester having at least one 1,4:3,6-dianhydrohexitol unit (A), at least one alicyclic diol unit (B) other than the 1,4:3,6-dianhydrohexitol units (A), and at least one terephthalic acid unit (C), wherein the molar ratio (A)/[(A)+(B)] is at least 0.05 and at most 0.30, said polyester being free of non-cyclic aliphatic diol units or comprising a molar amount of non-cyclic aliphatic diol units, relative to the totality of monomeric units in the polyester, of less than 5%, and with a reduced viscosity in solution (25° C.; phenol (50 wt. %): ortho-dichlorobenzene (50 wt. %); 5 g/L of polyester) greater than 70 mL/g.
