example 1
[0056] The resin monomer A structural formula that present embodiment will prepare is as follows:
[0057]
[0058]Step 1: Dissolve 20.0 g of larch tannin monosubstituted adamantane derivatives and 14.0 epichlorohydrin in ethanol in a three-necked flask, control the temperature of the heated water bath at 45 ° C, add 3.0 g of sodium hydroxide solid, and stir Reaction for 2 hours yielded the ring-opened intermediate. The reaction solution was distilled off under reduced pressure to remove excess epichlorohydrin and solvent.
[0059] Step 2: The intermediate was dissolved in tetrahydrofuran, and the temperature of the water bath was kept constant to 60° C. After adding 6.0 g of solid sodium hydroxide, a ring-closing reaction occurred to obtain product A with a yield of 89%.
example 2
[0061] The resin monomer A structural formula that present embodiment will prepare is as follows:
[0062]
[0063] Step 1: Dissolve 20.0 g of larch tannin monosubstituted adamantane derivatives and 14.0 epichlorohydrin in ethanol in a three-necked flask, control the temperature of the heated water bath at 45 ° C, add 3.0 g of sodium hydroxide solid, and stir Reaction for 2 hours yielded the ring-opened intermediate. The reaction solution was distilled off under reduced pressure to remove excess epichlorohydrin and solvent.
[0064] Step 2: The intermediate was dissolved in tetrahydrofuran, and the temperature of the water bath was kept constant to 60 ° C. After adding 10.0 g of solid sodium hydroxide, a ring-closing reaction occurred to obtain product A with a yield of 95.1%.
example 3
[0066] The resin monomer A structural formula that present embodiment will prepare is as follows:
[0067]
[0068] Step 1: Dissolve 20.0 g of larch tannin monosubstituted adamantane derivatives and 14.0 epichlorohydrin in ethanol in a three-necked flask, control the temperature of the heated water bath at 45 ° C, add 3.0 g of sodium hydroxide solid, and stir Reaction for 2 hours yielded the ring-opened intermediate. The reaction solution was distilled off under reduced pressure to remove excess epichlorohydrin and solvent.
[0069] Step 2: The intermediate was dissolved in tetrahydrofuran, and the temperature of the water bath was kept constant to 60° C. After adding 8.0 g of solid sodium hydroxide, a ring-closing reaction occurred to obtain product A with a yield of 94.7%.
