The polyglycidyl compounds according to the invention can be manufactured by reacting epihalogenohydrin with compounds of the formula IV ##STR1## or the formula V ##STR2## in which (1) n denotes 2, 3 or 4, (2) A represents a 2-valent, 3-valent or 4-valent organic radical which either contains a N-heterocyclic or cycloaliphatic ring or 2 N-heterocyclic rings or 2 phenylene rings, (3) either D denotes the --CH.sub.2.O.CO-- radical and m denotes the number 1, or D denotes the radical ##STR3## and m denotes O, and (4) R.sup.1 represents a divalent radical, which contains at least one hydantoin ring or uracil ring. During the reaction hydrogen halide splits off. From curable mixtures containing polyglycidyl compounds according to the invention and a curing agent such as hexahydrophthalic anhydride or phthalic anhydride are obtained products with good mechanical and electrical properties.
A curable mixture containing one or more compounds of the formula I ##STR25## in which n denotes 2, 3 or 4, A represents a 2-valent, 3-valent or 4-valent organic radical which either contains a N-heterocyclic or cycloaliphatic ring or 2 N-heterocylic rings or 2 phenylene rings, and R.sup.1 represents a divalent radical of the formula II ##STR26## in which a and b are identical or different and denote either 0 or 1, and in which R.sup.3 denotes a hydrogen atom or a methyl group and R.sup.2 denotes a nitrogen-free 2-valent radical which is necessary to add sufficient ring carbon atoms to complete a five-membered or six-membered ring, or of the general formula III ##STR27## in which either D denotes the --CH.sub.2.O.CO-- radical and m denotes the number 1, or D denotes the radical ##STR28## and m denotes 0, and R.sup.1 has the above meaning;
