Procedure

A one litter, three-neck flask was charged with 348 parts of tolylene diisocyanate (TDI) and heated to 80° C. Then, 260 parts of 2-hydroxyethyl methacrylate (2-HEMA), 0.07 part of tin octylate, and 0.05 part of hydroquinone were dripped while temperature was controlled to 80° C. After dripping, the sample was stirred at 80° C. for 3 hours and taken out. Thus, TDI-2-HEMA adduct was obtained.
