Abstract

See full text

A composition includes: at least one aliphatic or semi-aliphatic polyester containing at least 70 mol % of saturated aliphatic units, whereby the 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. A a method for producing one such composition and to the different uses of one such composition are also described.
