Abstract: Multilayer biodegradable film particularly suitable for use in the manufacture of packaging, comprising at least one layer (A) comprising at least one aliphatic-aromatic biodegradable polyester blended with an aliphatic polyester having at least 70% in moles of succinic acid, and at least one layer (B) comprising a polymer composition comprising an aliphatic-aromatic polymer. The film has high mechanical properties, in particular a high elastic modulus, and appreciable optical transparency properties.

Abstract: The present invention relates to a process for the reuse in polymerization of a biodegradable polymeric composition re) comprising a mixture of polyesters. The process comprises the steps of: 1) reacting said polymeric composition with water at a temperature higher than the melting temperature of at least one of said polyesters, obtaining a depolymerization product comprising monomers of said polyesters and/or their oligomers in a mixture, 2) separating from said depolymerization product a fraction comprising impurities and/or fillers, 3) subjecting said monomers and/or oligomers to polymerization, in quantities from 1% to 100% by weight, with respect to the mixture subjected to polymerization, obtaining a polymeric composition biodegradable. Further objects of the invention are the polymers obtained by means of said reuse process, the biodegradable polymeric compositions that comprise said polymers and the biodegradable articles obtained from said composition

Abstract: This invention relates to a process for the production of polyesters comprising an esterification/transesterification stage and a polycondensation stage, characterised 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.
