Definitions
- This invention relates to a polymer composition
- a polymer composition comprising at least two polyesters having improved mechanical properties, in particular good balancing between ultimate tensile strength, elastic modulus and elongation on fracture.
- This composition is particularly suitable for the production of manufactured articles such as for example films, moulded objects, thermoformed objects or expanded articles.
- polymer materials have become increasingly widespread as a result of their versatility, their ability to be easily processed and their low cost. Their increasing use in increasingly more technologically advanced sectors of application, however, requires a continuous development of new materials having increasingly better mechanical properties and performance during use, which are very often apparently irreconcilable; for example high elastic moduli coupled with excellent elongation on fracture and ultimate tensile strengths or good workability characteristics associated with a high continuing operating temperature.
- the widespread use of conventional polymer materials has also resulted in the occurrence of ever-increasing environmental problems associated with the consumption of resources (feedstocks) originating from non-renewable carbon.
- the polymer composition according to this invention is characterised by the fact that it comprises from 1 to 99%, preferably from 2 to 95% and more preferably from 5 to 50% by weight of at least a first aromatic polyester (AP) substantially comprising repeating units derived from at least one heterocyclic aromatic acid having multiple functional groups originating from a renewable source, and from 99 to 1%, preferably from 98 to 5% and more preferably from 95 to 50% by weight of at least a second aromatic aliphatic polyester (A APE).
