Embodiment 1
[0048] The molar ratio of MAn and St is 1:1, wherein MAn is 0.3065g and St is 0.325g; the initiator is azobisisobutyronitrile AIBN, 0.05g; the medium is isoamyl acetate, 45mL. Heating in a water bath and reacting at a temperature of 70Β° C. for 6 hours to obtain PMS microspheres of maleic anhydride / styrene alternating copolymer. Average particle size (Dn), dispersion coefficient (U) and polymerization yield (C p ), and the number average molecular weight (Mn) results of the polymer are shown in Table 1.
Embodiment 2
[0050] The molar ratio of MAn and St is 1:1, where MAn is 0.613g and St is 0.325g; the initiator is AIBN, 0.04g; the medium is isoamyl acetate, 45mL. Adopt water-bath heating, react 6 hours under the temperature of 70 β, obtain the average particle diameter (Dn) of PMS copolymer microsphere, dispersion coefficient (U) and polymerization yield (C p ), and the number average molecular weight (Mn) results of the polymer are shown in Table 1.
