More Information
Summary:Biodegradable aliphatic/aromatic copolyester comprising: A) an acid component comprising repeating units of : 1) 53 to 54 mol % of an aromatic carboxylic acid; 2) 47 to 36 mol % of an aliphatic acid at least 50% of which is azelaic acid ; B) a diol component selected from the group consisting of C3, C4 and C6 diols ; said AAPE being disintegrated according to the Standard ISO 20200 in 90 days. L'invention concerne un copolyester aromatique-aliphatique biodégradable comprenant : A) un composant acide comportant des unités récurrentes constituées de 1) 53-54 mol pour cent, 2) 36-47 mol pour cent d'un acide aliphatique composé à au moins 50 % d'acide azélaïque ; et B) un composant diol sélectionné dans le groupe comprenant des diols C3, C4 et C6. Ce polyester aromatique-aliphatique se désintègre en 90 jours selon la norme ISO 20200.
