Embodiment 1
[0033] (1) Dissolve bisphenol A diglycidyl ether in toluene by heating at 70°C; then dissolve potassium hydroxide in acrylic acid and add it dropwise to the toluene solution of bisphenol A diglycidyl ether, and add inhibitor Polymer hydroquinone, reflux reaction at 110~120°C for 48~60 h (nitrogen protection), the product is separated and purified by column chromatography to obtain bisphenol A diglycidyl ether monoacrylate, in which bisphenol A The molar ratio of diglycidyl ether and acrylic acid is 1:1, the amount of hydroquinone added is 0.3% of the total mass of bisphenol A diglycidyl ether and acrylic acid, and the amount of potassium hydroxide added is 0.6% of the mass of acrylic acid. Then take bisphenol A diglycidyl ether monoacrylate and styrene into a three-necked flask filled with tetrahydrofuran, add the initiator azobisisobutyronitrile, and react at 70°C for 48 h under reflux (nitrogen protection) to obtain styrene- Bisphenol A diglycidyl ether monoacrylate copolyme...
Embodiment 2
[0038] (1) Dissolve bisphenol A diglycidyl ether in toluene by heating at 70°C; then dissolve potassium hydroxide in acrylic acid and add it dropwise to the toluene solution of bisphenol A diglycidyl ether, and add inhibitor Polymerizing agent hydroquinone, reflux reaction at 110~120°C for 48~60 h (nitrogen protection), the product is separated and purified by column chromatography to obtain bisphenol A diglycidyl ether monoacrylate, in which bisphenol A The molar ratio of diglycidyl ether and acrylic acid is 1:0.75, the amount of hydroquinone added is 0.24% of the total mass of bisphenol A diglycidyl ether and acrylic acid, and the amount of potassium hydroxide added is 0.5% of the mass of acrylic acid. Then take bisphenol A diglycidyl ether monoacrylate and styrene into a three-necked flask filled with tetrahydrofuran, add the initiator azobisisobutyronitrile, and react under reflux at 70°C for 48 h (nitrogen protection) to obtain styrene- Bisphenol A diglycidyl ether monoac...
