[0052] Example 1
[0053] The mass ratio of PMV and total monomer is 1:1, the molar ratio of MAn and DVB is 1:1, among which PMV is 3g, MAn 1.56g, DVB-551.44g; initiator is AIBN, 0.06g; medium is butyl acetate and normal Heptane, butyl acetate 70vol.-%, n-heptane 30vol.-%, 56ml and 24ml, respectively. Heated in a water bath, reacted at 75°C for 10 hours, and dissolved PMV core with acetone to obtain the average particle size (d), wall thickness (d′) of the polymer hollow microspheres, and the polymerization yield (C p ), the results are shown in Table 1, and the transmission electron microscope photos of polymer hollow microspheres are shown in figure 1 . Take 0.3 g of the dried hollow microspheres and 0.3 g of ethylenediamine; the medium is tetrahydrofuran, 20 mL. Under magnetic stirring, react at room temperature for 30 minutes to obtain hollow polymer microspheres after amination. The infrared spectra of polymer hollow microspheres before and after amination are shown Picture ...
