Participants

Reaction Steps

1,517 Grams of an addition product of acrylic acid with propylene oxide [BLENMAR AP-550 of Nippon Oil and Fats Co. Ltd.; a compound of the formula (vii) wherein R4 is H, R5 is CH3 and h is 10], 1.00 g of hydroquinone monomethyl ether, 0.52 g of di-n-butyltin dilaurate and 222 g of isophorone diisocyanate were charged to a 4-liter four-necked flask equipped with a stirrer, a thermoregulator, a thermometer and a condenser, allowed to react with one another at 40 to 50° C. for 30 minutes and then the reaction was further continued at 80 to 90° C. to produce the third urethane acrylate [a compound of the formula (3) wherein R4 is H, R5 is CH3, A3 is an isophorone group, h is 10 ad j is 2].
