Patent ID: 8481653

Claim:
Polymeric composition comprising A) a biodegradable aliphatic/aromatic copolyester (AAPE) comprising: a) an acid component comprising repeating units of: 53 to 64 mol %, of a polyfunctional aromatic carboxylic acid; 47 to 36%, 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 and having: a density of less than a 1.22 g/cc; a number average molecular weight Mn of 40,000-140,000; an inherent viscosity of 0.8-1.5; a Elastic Modulus higher than 100 Pa; and a polydispersity index determined by means of GPC of between 1.8 and 25; B) at least one other polymer selected from other polyesters of the aliphatic/aromatic type or biodegradable polymers of natural origin or of synthetic origin.
