Abstract
Aliphatic-aromatic copolyester comprising the repeating units, which comprise a dicarboxylic component and a dihydroxylic component:—[—O—(R)—O—C(O)—(R)—C(O)—]——[—O—(R)—O—C(O)—(R)—C(O)—]—.The dihydroxylic component comprises units —O—(R)—O— and —O—(R)—O— from diols, wherein Rand Rindividually are selected from C-Calkylene, C-Ccycloalkylene, C-Coxyalkylene, heterocycles and mixtures thereof. The dicarboxylic component comprises units —C(O)—(R)—C(O)— from aliphatic diacids and units —C(O)—(R)—C(O)— from aromatic diacids, wherein Ris C-Calkylene and mixtures thereof. The aromatic diacids comprise at least one heterocyclic aromatic diacid of renewable origin, and preferably furandicarboxylic acid. The molar percentage of the aromatic diacids is >90% and <100% of the dicarboxylic component. The aliphatic-aromatic copolyester has appreciable workability, toughness and high values for ultimate tensile strength and elastic modulus. It can be mixed with other polymers.
