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 matrix composition for composites. Said products not only helpadvantageously 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. 本发明涉及双脱水己糖醇醚作为可交联的树脂、粘合剂、涂料或复合基质组合物中的反应性稀释剂的用途。这些产品不仅使得可能有利地降低所得混合物的粘度，而且与其他反应性稀释剂相比，它们还导致交联的混合物的玻璃化转变温度的非常小的降低，同时极大地改善了这些交联的混合物的机械特性如杨氏模量、拉伸强度、断裂伸长率和韧性。
