ABSTRACT:
Glycidyl polyethers of polyphenols are prepared by reacting at least one alkali metal salt of a polyphenol with at least one 1-halogeno-2,3-epoxyalkane, in an anhydrous and essentially aprotic reaction medium, and in the presence of a catalytically effective amount of a catalyst which comprises a cross-linked organic polymeric support, said support having a plurality of catalytically active functional groups covalently coupled thereto, the free valence of said functional groups having the structural formula: ##STR1## The subject process is admirably suited, for example, for the preparation of epoxy resins from the disodium salt of bisphenol A and epichlorohydrin.
