Abstract: Disclosed are aliphatic-aromatic biodegradable polyesters obtained from aliphatic dicarboxylic acids, polyfunctional aromatic acids of renewable origin and particularly 2,5-furan dicarboxylic acid, and diols. Also disclosed are blends of the polyesters with other biodegradable polymers of either natural or synthetic origin. The polyesters have properties and viscosity values that make them suitable, after adjusting their molecular weight, for use in numerous practical applications such as films, injection molded products, extrusion coatings, fibers, foams, thermoformed products, extruded profiles and sheets, extrusion blow molding, injection blow molding, rotomolding, stretch blow molding.

Abstract: Provided are polyesters selected from i) aliphatic polyesters wherein the dicarboxylic component and the diolic component are both aliphatic, the aliphatic dicarboxylic component comprising at least 20% by moles of 2-methylglutaric acid and up to 80% by moles of at least one second linear aliphatic saturated diacid; and ii) aliphatic-aromatic polyesters having a dicarboxylic component comprising repeating units deriving from at least one polyfunctional aromatic acid and at least one aliphatic diacid, and a diol component comprising repeating units deriving from at least one aliphatic diol, wherein said aliphatic diacid comprises a mixture consisting of at least 30% by moles of 2-methylglutaric acid and up to 70% by moles, with respect to the total moles of the aliphatic dicarboxylic component, of at least one second linear aliphatic saturated aliphatic diacids; and processes for production thereof. The polyesters have great toughness and high elongation at failure values.

Abstract: This invention relates to a process for the production of polyesters comprising an esterification/transesterification stage and a polycondensation stage, characterized in that the said polycondensation stage is carried out in the presence of a catalyst comprising a mixture of at least one Titanium-based compound and at least one Zirconium-based compound in which the Ti/(Ti+Zr) ratio by weights is equal to or greater than 0.01 and equal to or less than 0.70.
