Patent ID: 8846825

Claim:
Mixture comprising : (A) at least a first aliphatic-aromatic biodegradable polyester (A) of the diacid-diol type obtainable by a mixture comprising: a) at least one acid component having the following composition: a1) 51-95% by moles of aliphatic dicarboxylic acids, composed for at least 50% by moles of long chain diacids of renewable origin; a2) 5-49% by moles of polyfunctional aromatic acids; b) at least one diol; (B) at least a second biodegradable aliphatic-aromatic polyester (B) obtainable starting from a mixture comprising adipic acid, terephthalic acid and at least one aliphatic diol; (C) at least one polymer of natural origin (C); wherein the concentration of (A) varies, with respect to (A+B) in the interval between 5 and 95% in weight, wherein (C) is present in a quantity lower than 50% in weight with respect to (A+B+C), said mixture having a Melt Flow Index of 1.5-10 g/10 min.
