Abstract
Provided in the present invention are biodegradable polymer microspheres and a preparation method therefor. The preparation method comprises the step of polymerizing a biodegradable polymeric monomer in a mixed solution containing the biodegradable polymeric monomer, a water-soluble polymer and a catalyst. In the present invention, the monomer and the water-soluble polymer are mixed into a solution, and phase separation occurs, after the in situ polymerization of the monomer, to obtain the biodegradable polymer microspheres; the production process is simple and easy to control, without the need for an organic solvent; and the production process is environmentally friendly and the method is suitable for large-scale production.
