Abstract

Abstract New diglycidyl ethers of binuclear, five-membered or sixmembered, unsubstituted or substituted, N-heterocyclic compounds containing two NH groups in the molecule and containing added-on butene oxide, produced by reaction of binuclear, five-membered or six-membered, unsubstituted or substituted, N-heterocyclic compounds, such as bis-(hydantoin) or bis-(dihydrouracil) compounds, for example 1,1''-methylene-bis-(5,5dimethylhydantoin), 1,6-bis-(5,5-dimethylhydantoinyl-3)-hexane or Beta , Beta ''bis-(5,5-dimethylhydantoinyl-3)-diethyl ether, with butene oxide, for example 1,2-butene oxide, to give monoalcohols or dialcohols, and subsequent glydidylation of the OH groups or of the OH group and the NH group to give the corresponding glycidyl ethers.
