Abstract
Abstract Hydantoin diacrylate compounds of the formula ##STR1## wherein R 1 is hydrogen, alkyl containing 1 to 8 carbon atoms; R 2 is alkyl containing 5 to 8 carbon atoms; each of R 3 and R 4 independently are hydrogen or methyl and m and n each represent an integer of from 1 to 30 are prepared. The diacrylate compounds are liquid at room temperature, easily processable as adhesives, casting and laminating resins and when cured possess excellent resistance to water.
