FIELD: chemistry.
SUBSTANCE: invention relates to a polymer composition containing at least two polyesters, having improved mechanical properties, particularly good balance between tensile strength, modulus of elasticity and relative elongation at break, and is especially suitable for producing industrial articles such as, for example, films, injection moulded articles, thermoformed articles or expanded articles.
EFFECT: polymer composition contains at least two polyesters: one aromatic polyester, substantially containing repeating units formed from a heterocyclic aromatic polyfunctional acid of renewable origin, and a second aliphatic-aromatic polyester which is biodegradable.
