Abstract: Biodegradable block copolyesters abtained from crystalline blocks and amorphous blocks, wherein the repeating units of both blocks are of the decarboxylic acid/diol type. Said copolyesters are characterized by a melting temperature, equal to or less than 15% lower than the starting crystalline polymer temperature, and by increased tanaciy that makes them particularly useful in the production of different types of objects.
