Patent ID: 8461273

Claim:
Polymeric composition comprising A) a biodegradable aliphatic/aromatic copolyester (AAPE) comprising: a) an acid component comprising repeating units of: 49 to 66 mol % of an aromatic polyfunctional acid; 51 to 34% of an aliphatic acid, at least 70% of which is sebacic acid; b) butanediol; said AAPE being biodegradable according to the Standard ISO 14855 Amendment 1 of more than 40% in 30 days, with respect to cellulose used as reference; and having: a density of less than 1.22 g/cc; a number average molecular weight Mn of 40,000 to 140,000; an inherent viscosity of 0.8 to 1.5; and 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.
