The disclosed synthesis method for micron-level polymer microsphere comprises: using 5-10wt% glucose/water as medium system, 2-4.5wt% polyvinyl alcohol as stabilizer, 20~30wt% styrene, 0.3~1wt% divinylbenzens, and 0.5~1.5wt% azo-diisobutyronitrile; taking the suspension polymerization reaction in N2 atmosphere for 9-14h at 70-85Deg. Wherein, the product has particle size within 10-20nm and dispersion coefficient within 0.020-0.046. This invention simplifies the post-treatment, and solves the pollution of organic solvent efficiently.
