Example Embodiment
[0036] Example 1:
[0037] 1. Preparation of polymerizable photoinitiator
[0038] Weigh 12.70g (0.05mol) 4-(2,3-glycidoxy) benzophenone into a three-necked flask, heat to 85°C, add 5.10g (0.05mol) Malay dropwise while stirring A mixture of imide, 0.04g p-hydroxyanisole, 0.06g tetrabutylammonium bromide, drip in 60 minutes, after dripping, heat to 105℃, continue the reaction for 2h, dissolve the product with ether, and use 2 It was washed twice with% sodium hydroxide aqueous solution and deionized water, dried overnight with anhydrous magnesium sulfate, filtered, and steamed with a rotary evaporator to obtain 13.15 g of a light yellow viscous liquid.
[0039] 2. Preparation of light-curable resin
[0040] Weigh 11.11g (0.1mol) of vinylpyrrolidone, 0.18g (0.51mmol) of the above polymerizable photoinitiator and 0.01g (0.1mmol) of N,N-methylenebisacrylamide and place them in a three-necked flask. Under the protection of the atmosphere, the temperature was raised to 50°C, and 0.17g (1mm...

[0044] Example 2:
[0045] 1. Preparation of polymerizable photoinitiator
[0046] Weigh 15.24g (0.06mol) 4-(2,3-glycidoxy) benzophenone into a three-necked flask, heat up to 85°C, add 6.78g (0.06mol) N- dropwise while stirring The mixture of hydroxymaleimide, 0.05g p-hydroxyanisole and 0.08g tetrabutylammonium bromide was dropped within 60 minutes. After dropping, the temperature was raised to 105°C, the reaction was continued for 2h, and the product was dissolved with ether. It was washed twice with 2% aqueous sodium hydroxide solution and deionized water, dried overnight with anhydrous magnesium sulfate, filtered, and steamed with a rotary evaporator to obtain 16.33 g of a light yellow viscous liquid.
[0047] 2. Preparation of light-curable resin
[0048] Weigh 16.67g (0.15mol) of vinylpyrrolidone, 1.70g (4.64mmol) of the above polymerizable photoinitiator, and 0.18g (1.2mmol) of N,N-methylenebisacrylamide in a three-necked flask. Under the protection of the atmosphere, the temp...
