Diglycidyl ethers of ortho-substituted4-hydroxyphenylfluorenes, curable compositions comprising the diglycidyl ethers, and cured resins thereof have a high glass transition and an improved modulus of elasticity. The diglycidyl ethers of the invention for use in the curable composition of the invention can be mixtures obtained by the reaction of epihalohydrin with mixtures of fluorenebisphenols obtained by the reaction of one mole of one or more fluorenones with two or more moles or mixtures of two or more ortho-substituted phenols. The compositions are useful in molding and coating applications and in composite articles where the operating temperature of the article or material is elevated.
原代-4-羟基苯基芴的二缩水甘油醚、包含该二缩水甘油醚的可固化组合物及其固化树脂具有较高的玻璃化转变和更好的弹性模量。 用于本发明可固化组合物的本发明二缩水甘油醚可以是由表卤代烃与由一摩尔的一种或多种芴酮与两种或多种原代苯酚或两种或多种原代苯酚的混合物反应得到的芴双酚的混合物。 该组合物适用于模塑和涂层应用,以及物品或材料工作温度较高的复合物品。
