    • The main subject matter of the present invention is 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 invention 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.
    • 一种用于生产向上失水醚组合物,尤其isohexide缩水甘油醚的组合物过程中,所有这些的独到之处之一是在减压下进行共沸蒸馏。 搜索的组合物用于生产环氧树脂,其功能为,以形成一个三维大分子网络。 获得gemäß到处理的组合物是富含异山梨醇二环氧的衍生物的单环氧衍生物的损害,只有第一个参与的三维网络的形成。 交联密度因此增加,从而可以得到材料的所有这是更耐化学腐蚀和机械上更强并且具有与上失水醚组合物获得的雅丁到相同的材料相比更高的玻璃化转变温度(Tg) 现有技术。
