2,2-Bis(3-allyl-4-hydroxyphenyl)propane (308 g) was mixed with 2-methoxyethanol (10 g) and epichlorohydrin (740 g) and heated to 60° C. Sodium hydroxide flake (80 g) was added portionwise over 3 hours, and the mixture was stirred for a further 1/2 hour, also at 60° C. The mixture was filtered, the residue being washed with toluene, and the filtrate was evaporated to remove the solvents and the excess of epichlorohydrin. The concentrated product was filtered once more to give 334 g of 2,2-bis(3-allyl-4-(glycidyloxy)phenyl)propane, having an epoxide content of 4.03 equiv./kg and 4.5 allyl double bond equiv./kg.
