Patent

CA 2322810

The use of isosorbide esters, isosorbide polyesters, isosorbide ethers, isosorbide carbonates, isosorbide thioethers, isosorbide thioesters, isosorbide amides, isosorbide (thio)urethanes, isosorbide urea, isosorbide phosphates and isosorbide phosphonates as a plasticiser is described. Instead of isosorbide it is also possible for corresponding diols such as isomannide and similar compounds, in which the ring oxygen atoms of the isosorbide have been replaced by carbon or by other heteroatoms, to serve as a base. In particular, this relates to C3-C11 alkanoates of isosorbide, isomannide and the like. In particular, the compounds are used as a plasticiser in poly(vinyl chloride), optionally in conjunction with usual plasticisers such as dioctyl phthalates.

L'invention concerne des esters d'isosorbide, des polyesters d'isosorbide, des éthers d'isosorbide, des carbonates d'isosorbide, des thioéthers d'isosorbide, des thioesters d'isosorbide, des amides d'isosorbide, des (thio)uréthanes d'isosorbide, de l'urée d'isosorbide, des phosphates d'isosorbide et des phosphonates d'isosorbide utilisés comme plastifiants. A la place de l'isosorbide, on peut aussi utiliser comme base des diols correspondants, tels que l'isomanide ou des composés similaires, dans lesquels les atomes d'oxygène cycliques de l'isosorbide sont remplacés par un carbone ou par d'autres hétéroatomes. En particulier, l'invention porte sur des alcanoates C¿3?-C¿11? d'isosorbide, d'isomanide, etc. Ces composés sont notamment utilisés comme plastifiants dans un chlorure de polyvinyle conjugué éventuellement avec des plastifiants habituels tels que des dioctylphtalates.
