Procedure

N,N'-Diglycidyl-5,5-dimethylhydantoin (8.04 epoxide equiv./kg, 100 g), a diglycidyl ether of a polyoxypropylene glycol of average molecular weight 425 (3.07 epoxide equiv./kg, 200 g), bisphenol A diglycidyl ether (5.30 epoxide equiv./kg, 100 g), bisphenol A (100 g) and N-phenylimidazole (0.4 g) are stirred at 120° C. for 31/2 hours, by which time the epoxide content of the mixture is 2.67 epoxide equiv./kg.
