USE OF A COMPOSITION OF LOW-VISCOSITY BIS-ANHYDROHEXITOL ETHERS AS A REACTIVE DILUENT FOR CROSSLINKABLE RESIN, ADHESIVE, COATING AND MATRIX COMPOSITIONS FOR COMPOSITES

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.
