    Abstract: Disclosed are aliphatic-aromatic biodegradable polyesters obtained from aliphatic dicarboxylic acids comprising azelaic acid, sebacic acid, suberic acid, brassylic acid and their esters; polyfunctional aromatic acids of renewable origin and particularly 2,5-furan dicarboxylic acid, and diols, such as 1,2-ethanediol, 1,2-propanediol, 1,3-propanediol, 1,4-butanediol, 1,5-pentanediol, 1,6-haxanediol, 1,7-heptanediol, 1,8-octanediol, 1,9-nonanediol, 1,10-decanediol, 1,11-undecanediol, 1,12-dodecanediol, 1,13-tridecanediol, 1,4-cyclohexanedimethanol, propylene glycol, neopentyl glycol, 2-methyl-1,3-propanediol, dianhydrosorbitol, dianhydromannitol, dianhydroiditol, cyclohexanediol, cyclohexane-methanediol, aromatic diols such as phenols, and furan diol. 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: The invention relates to a process for the production of 1,4-butanediol comprising the preparation of a fermentation broth comprising 1,4-butanediol from renewable sources and water, separation of a liquid fraction comprising said 1,4-butanediol and water from one or more solid fractions, said liquid fraction comprising 2-pyrrolidone in an amount higher than 80 ppm, one or more passages of the resulting liquid fraction through a bed comprising one or more cation-exchange resins thereby providing an output pH of said liquid fraction from 4 to 2, one or more passages of the resulting liquid fraction through a bed comprising one or more anion-exchange resins thereby providing an output pH of said liquid fraction from 8 to 11, and the distillation of the liquid fraction thereby provided so as to obtain a composition having a concentration of said 1,4-butanediol higher than 99.0% by weight and comprising 2-pyrrolidone in an amount lower than 6 ppm. The resulting composition should exhibit an APHA color value after ageing of less than 30.
