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: This invention relates to a process for the selective hydrogenation of vegetable oils. In particular the invention relates to a process for the hydrogenation of vegetable oils which is capable of selectively converting polyunsaturated fatty acids into mono-unsaturated fatty acids and products obtained therefrom. The vegetable oils obtained from the process according to the invention have in particular a high mono-unsaturated fatty acids content and are particularly suitable for use as raw materials for the synthesis of chemical intermediates.
