Embodiment 1
[0022] Dissolve 44.4g of phthalic anhydride in 500ml of dichloromethane in a 2L flask with a condenser and mechanical stirring, then add 25.4g of dipentaerythritol (DPE), under nitrogen protection, heat to 60 ° C, slowly reflux, After reacting for 4 hours, it was cooled to room temperature, the insoluble solid was removed, and the clear liquid was transferred to a 2L flask. Subsequently, 42.6 g of glycidyl methacrylate and 1 g of p-toluenesulfonic acid were added, and reacted at 120° C. for 3 hours under nitrogen protection. Next, 44.4 g of phthalic anhydride was added, and reacted at 65° C. for 4 hours under the protection of nitrogen. After the reaction was completed, the reaction solution was cooled to room temperature, slowly poured into a large amount of water, and the precipitate was collected and fully washed with water. Drying in a vacuum oven gave the product as a pale yellow solid.
[0023] The structure of the product was confirmed by NMR.

Embodiment 2
[0027] In a 2L flask with a condenser and mechanical stirring, dissolve 74g of phthalic anhydride in 500ml of toluene, then add 25.4g of dipentaerythritol (DPE), heat to 60°C under nitrogen protection, slowly reflux, and react for 4 hours Cool to room temperature, remove insoluble solids, and transfer the supernatant to a 2L flask. Subsequently, 71 g of glycidyl methacrylate and 2 g of anhydrous aluminum chloride were added, and reacted at 120° C. for 3 hours under nitrogen protection. Subsequently, 14.8 g of phthalic anhydride was added, and reacted at 65° C. for 4 hours under the protection of nitrogen. After the reaction was completed, the reaction solution was cooled to room temperature, slowly poured into a large amount of water, the precipitate was collected, washed with water, and dried in a vacuum oven to obtain a light yellow solid product.
[0028] The product was confirmed by NMR.

Embodiment 3
[0032] Dissolve 29.6g of phthalic anhydride in 500ml of xylene in a 2L flask with a condenser and mechanical stirring, then add 25.4g of dipentaerythritol (DPE), heat to 70°C under nitrogen protection, and slowly reflux, reaction 3 After 1 hour, cool to room temperature, remove the insoluble solids, and transfer the supernatant to a 2L flask. Subsequently, 36.4g of 3,4-epoxycyclohexyl methacrylate and 1g of boron trifluoride were added, and reacted at 120° C. for 4 hours under nitrogen protection. Subsequently, 87.2 g of phthalic dianhydride was added, and reacted at 65° C. for 4 hours under the protection of nitrogen. After the reaction was completed, the reaction solution was cooled to room temperature, slowly poured into a large amount of water, the precipitate was collected, washed with water, and dried in a vacuum oven to obtain a light yellow solid product.
[0033] The product was confirmed by NMR.
