biodegradable composition comprising polymers of natural origin and aliphatic-aromatic copolyesters. the present invention relates to a biodegradable composition comprising at least one polymer of natural origin and at least one aliphatic-aromatic ester obtained from mixtures comprising aliphatic diols, polyfunctional aromatic acids and at least two aliphatic dicarboxylic acids, at least one of the which is long chain. such composition combines improved biodegradability, excellent mechanical properties, a high level of industrial processability, (imitated environmental impact, as well as stability of physical properties under the influence of environmental factors. |
