Hydroquinone → Urethane acrylate

Participants

Reaction Steps

192.4 g of 1,6-hexanediol and 166.6 g of adipic acid were placed in a reaction vessel and reacted for 6 hours at 220° C. while dehydrating and condensing to obtain 318 g of polyester. 222 g (1 mole) of isophorone diisocyanate were added thereto and reacted for 2 hours at 80° C. Moreover, 116 g (1 mole) of 2-hydroxyethyl acrylate and 1.4 g of hydroquinone were further added thereto and reacted for 3 hours at 80° C. while blowing in air to obtain a urethane acrylate (C-1) having acryloyl groups on both ends of a molecule thereof.
