Plasticizing of aliphatic polyesters with alkyl esters of dianhydro hexitols

The invention relates to a composition comprising: at least one aliphatic or semi-aliphatic polyester containing at least 70 mol % of saturated aliphatic units, whereby said units can be obtained by polycondensation of monomers selected from among saturated hydroxyalkanoic acids having formula HO -...

Beschreibung
Zusammenfassung:	The invention relates to a composition comprising: at least one aliphatic or semi-aliphatic polyester containing at least 70 mol % of saturated aliphatic units, whereby said units can be obtained by polycondensation of monomers selected from among saturated hydroxyalkanoic acids having formula HO - CxH2x-COOH, saturated dicarboxylic acids having formula HOOC-CxH2x-COOH, and saturated diols having formula HO - CxH2x-OH, wherein x = 1 - 20, preferably 1 - 6, the rest of the units being formed by aromatic units; and at least one alkyl ester of 1,4 :3,6-dianhydro hexitol selected from among alkyl monoesters and alkyl diesters of isosorbide, isomannide and isoidide. The invention also relates to a method for producing one such composition and to the different uses of one such composition.
