Embodiment 1
[0035] A polyalkenyl ether compound P1 in this embodiment is prepared by click alkoxylation polymerization of a di-alkyne compound and a di-hydroxy compound, and the reaction equation is as formula (1):
[0036]
[0037] Wherein, the synthesis method of monomer M1 can be synthesized according to the synthesis method of the applicant in the published literature (Polym.Chem., 2012, 3, 1075-1083); M2 is 1,8-octanediol, which can be purchased from the market In this example, it was purchased from Aladdin Company; the catalyst DABCO can be purchased from the market, and in this example and the examples described below, it was purchased from TCI (Shanghai) Chemical Industry Development Co., Ltd.
[0038] The preparation steps of described polyalkene ether compounds are as follows:
[0039] Add 44.4 mg (0.2 mmol) of monomer M1, 29.2 mg (0.2 mmol) of monomer M2 and 0.4 mL of tetrahydrofuran into a 10 mL polymerization tube. After the monomers are completely dissolved, the temperatu...
Embodiment 2
[0042] A polyalkenyl ether compound P2 in this example is prepared by click alkoxylation polymerization of a di-alkyne compound and a di-hydroxy compound, and the reaction formula is as follows (2):
[0043]
[0044] Wherein, the synthesis method of the monomer M1 is the same as that of Example 1; M3 is 1,12-dodecanediol, which can be purchased from the market, and in this example is purchased from Aladdin Company.
[0045] The preparation steps of described polyalkene ether compounds are as follows:
[0046] Add 44.4 mg (0.2 mmol) of monomer M1, 40.5 mg (0.2 mmol) of monomer M3 and 0.4 mL of tetrahydrofuran into a 10 mL polymerization tube. After the monomers are completely dissolved, the temperature is raised to 25°C. 2.24mg (0.02mmol) DABCO was dissolved in 0.1mL tetrahydrofuran. After the system was kept at constant temperature, the DABCO solution was added to the above monomer solution and reacted for 1 hour. After the reaction was finished, the reaction solution was ...
Embodiment 3
[0049] A polyalkenyl ether compound P3 in this embodiment is prepared by click alkoxylation polymerization of a di-alkyne compound and a di-hydroxy compound, and the reaction formula is as formula (3):
[0050]
[0051] Wherein, the synthesis method of monomer M1 is the same as in Example 1; M4 is dibromoneopentyl glycol, which can be purchased from the market, and in this example, it is purchased from Aladdin Company.
[0052] The preparation steps of described polyalkene ether compounds are as follows:
[0053] Add 44.4 mg (0.2 mmol) of monomer M1, 52.4 mg (0.2 mmol) of monomer M4 and 0.4 mL of tetrahydrofuran into a 10 mL polymerization tube. After the monomers are completely dissolved, the temperature is raised to 25°C. 2.24mg (0.02mmol) DABCO was dissolved in 0.1mL tetrahydrofuran. After the system was kept at constant temperature, the DABCO solution was added to the above monomer solution and reacted for 1 hour. After the reaction, the reaction solution was diluted w...
