The invention relates to a novel methylated cyclodextrin and to a novel method used for the production thereof. The invention also relates to the use of said methylated cyclodextrin for the solubilisation of lipophilic compounds, or carriers of at least one lipophilic group. The invention further relates to a composition comprising said methylated cyclodextrin, particularly a pharmaceutical composition.

Methylated cyclodextrins and methods for the production thereof

The present invention relates to the use of bis-anhydrohexitol ethers as reactive diluents in a crosslinkable resin, adhesive, coating or composite matrix composition. Not only do these products make it possible to advantageously reduce the viscosity of the mixtures obtained, but they also lead to a very small reduction in the glass transition temperature of the crosslinked mixtures, compared to other reactive diluents, while spectacularly improving the mechanical properties of the latter such as the Young's modulus, the tensile strength, the elongation at break and the toughness.

Use of a composition of low-viscosity bis-anhydrohexitol ethers as a reactive diluent for crosslinkable resin, adhesive, coating and matrix compositions for composites

A process for producing bis-anhydrohexitol ether compositions and in particular isohexide glycidyl ether compositions, one of the originalities of which is azeotropic distillation carried out under reduced pressure. Such compositions are used to produce epoxy resins, the function thereof being to form a three-dimensional macromolecular network. The compositions obtained according to the process are rich in diepoxy derivatives of isosorbide to the detriment of monoepoxy derivatives, only the first participating in the formation of the three-dimensional network. The crosslinking density is therefore increased, thereby making it possible to obtain a material which is more chemically resistant and mechanically stronger and which has a higher glass transition temperature (Tg), compared with the same materials obtained with bis-anhydrohexitol ether compositions according to the prior art.
