Embodiment 1
[0063] The preparation of a kind of borneol-based polymer with acid degradation properties, the reaction scheme is as follows figure 1 shown, as follows:
[0064] (1) at room temperature, weigh 0.3031g of borneol, dissolve in 30mL of methylene chloride, add 20.21mg of catalyst p-toluenesulfonic acid, and stir for 2 hours under the condition that rotating speed is 1000r / min to obtain solution A;
[0065] (2) At room temperature, 7.794 g of diethylene glycol monovinyl ether was dissolved in 20 mL of dichloromethane solvent to obtain solution B; under the condition that the reaction system was 0 °C and 1000 r / min, the Constant pressure funnel, slowly drop solution B into solution A, the reaction time is 4 hours;
[0066] (3) To the reaction system, add saturated aqueous sodium bicarbonate solution in batches to pH=8, to remove p-toluenesulfonic acid, spin to evaporate, extract 3 times with 3×10 mL of dichloromethane, collect the organic layer, add 3 g of anhydrous sulfuric acid ...
