Summary:Aliphatic-aromatic polyesters with a controlled amount of mixed residual cyclic oligomers having certain ratios between cyclic oligomers containing at least two types of dicarboxylic aliphatic units having a molecular mass below 1000 and cyclic oligomers containing only one type of dicarboxylic aliphatic unit having a molecular mass below 1000, and process for their preparation. L'invention concerne des polyesters aliphatiques-aromatiques à quantité contrôlée d'oligomères cycliques résiduels mélangés ayant certains rapports entre des oligomères cycliques contenant au moins deux types d'unités aliphatiques dicarboxyliques ayant une masse moléculaire inférieure à 1000 et des oligomères cycliques ne contenant qu'un seul type d'unité aliphatique dicarboxylique ayant une masse moléculaire inférieure à 1000, et un procédé pour leur préparation.
