Abstract

A method for producing a composition of diesters, includes a step including the esterification of 1,4:3,6-dianhydrohexitol by a composition of carboxylic acids, the composition including: at least an acid having formula C7H15COOH (X) and an acid having formula C9H19COOH (Y), the mass ratio (X)/(Y) varying between 10/90 and 90/10.

Claims

1. A composition comprising:

at least 80% up to about 99% by mass of diesters relative to a total mass of the composition, wherein said composition comprises;

from 5% to 57% by mass of diester (A) of formula;

2. The composition as claimed in claim 1, comprising:

from 5% to 57% by mass of diester (A);

from 37% to 54% by mass of diester (B); and

from 5% to 57% by mass of diester (C).

3. The composition as claimed in claim 1, comprising:

from 5% to 43% by mass of diester (A);

from 37% to 53% by mass of diester (B); and

from 11% to 57% by mass of diester (C).

4. The composition as claimed in claim 1, comprising:

from 5% to 31% by mass of diester (A);

from 37% to 52% by mass of diester (B); and

from 19% to 57% by mass of diester (C).

5. The composition as claimed in claim 1, wherein:

diester (A) has the following formula;

6. The composition as claimed in claim 1, wherein said polymer is selected from the group consisting of vinyl polymers, polyurethanes, polyesters, cellulose-based polymers, starches, acrylic polymers, polyacetates, natural or synthetic rubbers, polyamides, and mixtures of these polymers.

7. The composition as claimed in claim 1, wherein said polymer is polyvinyl chloride.
