Examples
Synthetic example 1
[0138] (Synthesis example 1 (production of polyurethane prepolymer A))
[0139] 100 parts by weight of polytetramethylene ether glycol (manufactured by Mitsubishi Chemical Corporation, "PTMG-2000") and 0.01 part by weight of dibutyltin dilaurate were charged into a 500-mL separable flask as a polyol, Stir and mix at 100° C. for 30 minutes under vacuum (below 20 mmHg). Thereafter, the pressure was set to normal pressure, 26.5 parts by weight of Pure MDI (manufactured by Nisso Shoji Co., Ltd.) was added as a diisocyanate, and the mixture was stirred at 80° C. for 3 hours and reacted to obtain a polyurethane prepolymer A (weight average molecular weight: 2700).
Synthetic example 2
[0140] (Synthesis example 2 (production of polyurethane prepolymer B))
[0141] 100 parts by weight of polypropylene glycol (manufactured by Asahi Glass Co., Ltd., "EXCENOL 2020") and 0.01 part by weight of dibutyltin dilaurate as a polyhydric alcohol were added to a 500-mL separable flask, under vacuum (20mmHg or less), 100°C Stir for 30 minutes and mix. Thereafter, the pressure was set to normal pressure, 26.5 parts by weight of Pure MDI (manufactured by Nisso Shoji Co., Ltd.) was added as a diisocyanate, and the mixture was stirred at 80° C. for 3 hours to allow a reaction to obtain a polyurethane prepolymer B (weight average molecular weight: 2900).
Synthetic example 3
[0142] (Synthesis example 3 (production of polyurethane prepolymer C))
[0143] In the reaction container containing the polyurethane prepolymer A obtained in the same manner as in Synthesis Example 1, 1.3 parts by weight of hydroxyethyl methacrylate and N-nitrosophenylhydroxylamine aluminum salt (Wako Junyaku Kogyo Co., Ltd., "Q-1301") 0.14 parts by weight, stirred and mixed at 80° C. for 1 hour under a nitrogen stream to obtain a polyurethane prepolymer C (weight average molecular weight) having isocyanate groups and methacryloyl groups at molecular terminals 3100).
