الإجراء التجريبي

500 g of polyethylene glycol having a molecular weight of about 1,000 and 168 g (1 mole) of hexamethylene diisocyanate were placed in a reaction vessel and reacted for 2 hours at 80° C. Moreover, 116 g (1 mole) of 2-hydroxyethyl acrylate and 1.7 g of hydroquinone were added thereto and reacted for 3 hours at 80° C. while blowing in air to obtain a urethane acrylate (A-2) having acryloyl groups on both ends of a molecule thereof. The weight average molecular weight of the urethane acrylate (A-2) was 1,900.
