    摘要: A polymer composition comprising at least two polyesters having improved mechanical properties including a good balance between ultimate tensile strength, elastic modulus and elongation on failure. In particular, the composition comprises from 1 to 99% by weight of at least one aromatic polyester (AP) comprising units from a diol component and units from an acid component, the units from the acid component comprising from 70 to 100 mol % of repeating units from at least one heterocyclic polyfunctional aromatic acid of renewable origin and from 99 to 1% by weight of at least a second aliphatic-aromatic polyester (AAPE). This composition is suitable for producing articles such as films, moulded objects, thermoformed objects or expanded articles. The heterocyclic aromatic acid is 2,5-furandicarboxylic acid and the aliphatic-aromatic polyester is biodegradable and is a copolyester comprising repeating units from aromatic acid of the phthalic acid type, aliphatic diacids, and aliphatic diols.

    摘要: A process for the production of carboxylic acids and their derivatives comprising the steps of: (c) reacting a derivative of an unsaturated fatty acid with an oxidizing compound in the presence of a catalyst capable of catalysing the reaction of oxidation of the double olefinic bond of the derivative of the unsaturated fatty acid so as to obtain as intermediate product of reaction a vicinal diol; and (d) reacting said intermediate compound with oxygen, or a compound containing oxygen, in the presence of a catalyst capable of catalysing the reaction of oxidation of the hydroxyl groups of the vicinal diol to carboxylic groups, characterized in that both of the steps (a) and (b) are carried out in the absence of added organic solvent and in that the water/diol ratio in the reaction of step (b) is less than 1:1.
