description The present invention relates to the use of bis-anhydrohexitol ethers as reactive diluents in a crosslinkable resin, adhesive, coating or matrix composition for composites. Said products not only help advantageously reduce the viscosity of the obtained mixtures, but also produce 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, tensile strength, elongation at break and toughness. La presente invención se refiere al uso de éteres de bis-anhidrohexitol como diluyentes reactivos en una composición reticulable de resina, adhesivo, recubrimiento o matriz para materiales compuestos. Estos productos no solo posibilitan la reducción de manera conveniente de la viscosidad de las mezclas obtenidas, sino que también conllevan una reducción muy pequeña en la temperatura de transición vítrea de las mezclas reticuladas, en comparación con otros diluyentes reactivos, a la vez que mejoran de manera espectacular las propiedades mecánicas de las últimas tales como el módulo de Young, la resistencia a la tracción, la elongación a la rotura y la tenacidad.
