Method for producing biodegradable polymer filler, and method for producing injection containing same |
| abstract |
Provided is a method for producing a biodegradable polymer filler composed of spherical porous particles, the method comprising: a step for preparing a first solution containing a biodegradable polymer and an organic solvent; a step for preparing a second solution containing at least one water-soluble compound selected from among a water-soluble polymer and a water-soluble monomer; a step for injecting the first solution and the second solution into a continuous reactor; a step for using Couette-Taylor flow to generate biodegradable polymer microparticles in the continuous reactor from the first solution and the second solution; a step for discharging, from the continuous reactor, a first composition containing the biodegradable polymer microparticles; a step for separating the biodegradable polymer microparticles from the first composition; a step for mixing the separated biodegradable polymer microparticles and a biocompatible carrier to prepare a second composition; a step for injecting the second composition into a mold and freezing the same to prepare a frozen product; and a step for removing water from the frozen product to prepare a biodegradable polymer filler. |
