Abstract
An advanced addition product containing 1,2-epoxide groups is prepared from the reaction of a hydantoin compound of the formula ##STR1## wherein R.sub.1 is hydrogen, alkyl containing 1 to 8 carbon atoms or cycloalkyl containing 5 to 6 carbon atoms; and R.sub.2 is alkyl containing 5 to 8 carbon atoms or cycloalkyl containing 5 to 6 carbon atoms; with less than 1.0 equivalents of NH groups per epoxide group the hydantoin compound, of a binuclear bis-hydantoin of the formula ##STR2## wherein R.sub.3 and R.sub.4 are selected from the group consisting of hydrogen or alkyl of 1 to 4 carbon atoms; or together R.sub.3 and R.sub.4 form tetramethylene or pentamethylene; and A is selected from the group consisting of alkylene, alkylidine or alkylidene substituted by one or more halogen atoms.
