    Abstract: Epoxy resins comprising a diglycidyl ether of Formula 1 as defined herein are described. The diglycidyl ether contains a cycloaliphatic ring of 3-5 carbon atoms. The epoxy resins are made by a method comprising the steps of: (a) forming a reaction mixture comprising a diol of Formula 3 as defined herein, an epihalohydrin, a phase transfer catalyst, and optionally an organic solvent; (b) contacting a basic acting substance and water with the reaction mixture of step (a); (c) washing the mixture of step (b) with an aqueous solvent to substantially remove salts; and (d) isolating the epoxy resin. Curable and cured compositions comprising the epoxy resins are also disclosed. The epoxy resins have increased glass transition temperatures and reduced viscosity compared to epoxy resins derived from cyclohexanedimethanol.

    Abstract translation: 描述了包含本文所定义的式1的二缩水甘油醚的环氧树脂。 二缩水甘油醚包含3-5个碳原子的脂环族环。 环氧树脂通过包括以下步骤的方法制备：（a）形成包含如本文所定义的式3的二醇，表卤代醇，相转移催化剂和任选的有机溶剂的反应混合物; （b）将碱性作用物质和水与步骤（a）的反应混合物接触; （c）用水性溶剂洗涤步骤（b）的混合物以基本上除去盐; 和（d）分离环氧树脂。 还公开了包含环氧树脂的可固化和固化的组合物。 与衍生自环己烷二甲醇的环氧树脂相比，环氧树脂具有增加的玻璃化转变温度和降低的粘度。
