Abstract

A study was performed to demonstrate how scR22 can be used as the solvent for the ring-opening solution polymerization of L-LA, followed by the in situ fabrication of PLLA microspheres, without any residual monomer and solvent, by using a continuous SAS process. It was emphasized that the process presents several advantages compared to the traditional polymerization in organic solvents or in ScCO2 for preparing PLLA microspheres.
