    Abstract: A process for preparing thermoset composite articles under relatively mild conditions includes exposing a laminate containing a partially-cured thermosettable resin and a fibrous substrate to an elevated temperature which increases over time, the elevated temperature being below the glass transition temperature of the resin but sufficient to promote further curing and increase the glass transition temperature thereof to the ultimate glass transition temperature of the resin. The temperature of exposure is generally increased at a rate which maintains the temperature within about 20.degree. C. below the glass transition temperature of the thermoset-table resin, so that cure of the resin proceeds in the glassy state. The pressure during the process is generally maintained below about 50 psi and is preferably atmospheric pressure. The process enables the production of thermoset composite articles suitable for high-performance applications without lengthy autoclave treatments.

    Abstract: The preparation of solid saturated epoxy resin compositions, which when cured with conventional epoxy curing agents yield coatings exhibiting improved weatherability, i.e., better gloss retention and better chalk resistance, are described. The solid saturated epoxy resins are prepared by reacting liquid or semisolid saturated epoxy resins with a dihydroxy phenol such as resorcinol in the presence of a suitable catalyst.

    Abstract: A process is disclosed for preparing a low-chlorine epoxy resin which employs crystallization of the epoxy from solution in a finishing step of the preparation process. The process involves (a) contacting, in a basic reaction medium, epichlorohydrin and a biphenol to produce a reaction product mixture containing a diglycidyl ether of the biphenol; (b) dissolving the diglycidyl ether in an organic solvent and, optionally, contacting the diglycidyl ether with a dehydrochlorination agent; and (c) reducing the temperature of the organic solvent so as to effect crystallization of a low-chlorine fraction of the diglycidyl ether.
