Rapid Curing Epoxy Resins Derived from Resorcinol.
Abstract
Epoxy resins that can be cured rapidly at room temperature are highly desirable from the production standpoint. A new epoxy resin, diglycidyl ether of 4-methylol resorcinol was synthesized. In the molecule, the hydroxyl from the methylol substituent is proximate to one of the epoxide rings to catalyze ring opening during curing. The new resin is of moderate viscosity due to a relatively low molecular weight, and at room temperature can be cured approximately fifty times faster than the standard bisphenol A-type epoxy resins and three times faster than the fastest curing commercial epoxy resins known. The synthetic intermediate, diglycidyl ether of beta-resorcylaldehyde, is an epoxy resin itself. (Modified author abstract)
