Preparation of glycidyl polyethers of polyphenols

A process for the preparation of glycidyl polyethers of polyphenols, comprising 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:

• ##STR19## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.6 and R.sub.7, which are identical or different, are each a hydrogen atom or an alkyl radical having from 1 to 4 carbon atoms, R.sub.5 and R.sub.8, which are identical or different, represent a hydrogen atom, an alkyl or cycloalkyl radical having from 1 to 12 carbon atoms, a phenyl radical or radical C.sub.6 H.sub.5 --C.sub.2 H.sub.2q -- or C.sub.q H.sub.2q+1 --C.sub.6 H.sub.4 --, in which q ranges from 1 to about 12, and n, m and p, which are identical or different, range from 1 to 10.
