Patent ID: 8466237

Claim:
Polymeric composition comprising A) a biodegradable aliphatic/aromatic copolyester (AAPE) comprising: a) an acid component comprising repeating units of: 49 to 63 mol % of a polyfunctional aromatic acid; 51 to 37% of an aliphatic acid at least 50% of which is brassylic acid; b) a diol component; said AAPE being disintegrated according to the Standard ISO 20200 in 90 days; and having: a density of less than or equal to 1.18 g/cc; a number average molecular weight Mn of 40,000-140,000; an inherent viscosity of 0.8-1.5; 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.
