Abstract:
A manufacturing method for porous resin microparticles comprising steps of: heating a polyester thermoplastic resin having biodegradability to a temperature of 80° C. or higher and 200° C. or lower in a glycol ether solvent to obtain a solution, and cooling the solution to precipitate the polyester thermoplastic resin as porous resin microparticles.
