Abstract
Abstract Diglycidyl and tetraglycidyl compounds are obtained by glycidylating diurethanes obtained from 1 mol of a diisocyanate and 2 mols of a 3-hydroxyalkylhydantoin or 3hydroxyalkyldihydrouracil in a known manner with epichlorohydrin or Beta -methylepichlorohydrin. The new epoxide resins can be cured with the customary curing agents for epoxides to give moulded materials having valuable mechanical and dielectric properties and are above all suitable for use as powder resins, such as fluidised bed powders and compression moulding powders.
