Embodiment 1
[0159] Into the high vacuum reactor, add 1 gram of epoxy monomer (4.5 mmol, x=2), the monomer and benzene azeotropically remove water. Add 100 microliters of 2-methyl-3-butene-2-alcohol potassium initiator (this reagent is commercially available, dissolved in 1M tetrahydrofuran THF, take 0.1mmol) and 1 milliliter of ultra-dry toluene and 1 Mg Octadecyl Crown Ether Hexa Catalyst. The reactor was reacted at 0°C for 5 days. After the reaction, 0.1 ml of allyl bromide and 5 mg of sodium hydride were added to the system, and stirred overnight at room temperature to terminate the reaction. The solvent was distilled off under reduced pressure, and the mixture was liquid-separated with chloroform and water. The organic phase was collected and purified by distillation under reduced pressure. The concentrate was further vacuum-dried to obtain a colorless viscous liquid product with a yield of 98%. The equation of this reaction is shown in the following formula (1).

Embodiment 2
[0165] Add 1 gram of epoxy monomer (4.5 mmol, x=3) into the high vacuum reactor, and the monomer and benzene azeotropically remove water. Under the protection of nitrogen, 100 μl of initiator 2-(1-diethoxy)-potassium ethoxide (1M dissolved in THF, 0.1 mmol) and 1 mg of phase transfer catalyst octadecadecron6 were added. 1 ml of toluene was transferred into the system, and the reactor was placed at room temperature (25° C.) for 12 hours of reaction. After the reaction, 0.1 ml of ultra-dry methanol was added to the system to terminate the reaction. The solvent was distilled off under reduced pressure, and the mixture was liquid-separated with chloroform and water. The organic phases were collected and distilled under reduced pressure. The product was dissolved in 20 ml of hydrochloric acid in a water / THF mixed solution (0.5 M concentration), and stirred at room temperature for 1 day to complete the terminal hydrolysis reaction. After the reaction, the mixed solution was washe...
Embodiment 3
[0171] Add 1 gram of monomer (4.5 mmol, x=3) into the high vacuum reactor, and remove water by azeotroping the monomer and benzene. Under the protection of nitrogen, 100 microliters of initiator potassium 2-methyl-3-buten-2-oxide (1 M dissolved in THF, 0.1 mmol) and 1 mg of catalyst octadecadecron6 were added. 1 ml of toluene was transferred into the system, and the reactor was placed at room temperature (0° C.) for 12 hours. After the reaction, 0.1 ml of ultra-dry methanol was added to the system to terminate the reaction. The solvent was distilled off under reduced pressure, and the mixture was liquid-separated with chloroform and water. The organic phases were collected and distilled under reduced pressure. The product was dissolved in 20 ml of hydrolysis catalyst tert-butyldimethylsilyl trifluoromethanesulfonate (TBDMSOTf) / dichloromethane mixed solution (1M concentration), and stirred at room temperature for 1 day to complete the terminal hydrolysis reaction. After the ...
