Reaction Steps
Adipic acid (73 g) is added in portions with stirring to N,N'-diglycidyl-5,5-dimethylhydantoin (8.04 epoxide equiv./kg, 200 g) containing N-phenylimidazole (0.4 g), the temperature is kept at 100° C. and the addition is carried out over 40 minutes. The heating is maintained at 100° C. for a further 41/3 hours by which time the epoxide content has fallen to 2.35 equiv./kg.
