Participants

Conditions

Temperature: 70 °C

Procedure

Into a flask similar to the flask in Synthesis Example 1 were charged 50 parts of toluene, 50 parts of hexamethylene diisocyanate subjected to isocyanurate modification (TAKENATE D-170N), 94 parts of polycaprolactone-modified hydroxyethyl acrylate (PLACCEL FA2D), 0.02 parts of dibutyltin laurate, and 0.02 parts of hydroquinone monomethyl ether. The mixture was maintained at 70° C. for 5 hours to complete the reaction, and 94 parts of toluene were added to obtain a urethane acrylate containing 50% by weight of solid.
