Glycidylethers of fluorene-containing bisphenols.

摘要

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.
