To date, in view of the continued growth of the production and use of plastic materials, the exploitation of non-renewable sources for their implementation and subsequent disposal of these huge piers, are extremely current issues and still far from being resolved. In parallel, the world of research, as well as that of industry, are moving more and more towards solutions that reduce the environmental impact as much as possible, both in terms of resource use, that of terrestrial and marine environmental protection. In this direction bioplastics, i.e. plastics from renewable sources or biodegradable (or both) and possibly recyclable, represent a highly sustainable answer to these problems. A monomer from renewable sources which allows the realization of polymers with excellent mechanical and barrier properties is the 2,5-furandicarbossilico acid, whose polyesters are not, however, biodegradable. Conversely, aromatic/aliphatic biodegradable copolymers are already present on the market, but they are not completely obtainable from renewable sources. In this context, the present research work focused on the study of new aromatic/aliphatic copolymers completely bio-based and biodegradable. The synthesized materials were also subjected to several analyzes, in order to study their properties in relation to possible industrial applications as substitutes for Ecoflex. In particular, they have been characterized from the structural, thermal, mechanical, point of view and finally it was evaluated their compostability. The results obtained have been correlated to chemical structure, i.e to copolymer composition.
