Title (EN) PLASTICIZING OF ALIPHATIC POLYESTERS WITH ALKYL ESTERS OF DIANHYDRO HEXITOLS
(FR) PLASTIFICATION DE POLYESTERS ALIPHATIQUES PAR DES ESTERS ALKYLIQUES DE DIANHYDROHEXITOLS
Abstract: front page image
(EN)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.
(FR)L'invention concerne une composition comprenant, - au moins un polyester aliphatique ou semi-aliphatique, contenant au moins 70% en moles de motifs aliphatiques saturés, ces motifs étant susceptibles d'être obtenus par la polycondensation de monomères choisis parmi : les acides hydroxyalcanoïques saturés de formule : HO - CxH2x-COOH, les acides dicarboxyliques saturés de formule : HOOC-CxH2x-COOH et les diols saturés de formule : HO - CxH2x-OH où x = 1 - 20, de préférence 1 - 6, la partie restante des motifs étant formée par des motifs aromatiques, et - au moins un ester alkylique de 1,4 :3,6-dianhydrohexitol choisi parmi les monoesters alkyliques et les diesters alkyliques d'isosorbide, d'isomannide et d'isoidide. L'invention concerne également un procédé de fabrication d'une telle composition et différentes application d'une telle composition.
