摘要

Process for the preparation and use of biodegradable microspheres of biodegradable microspheres monodispersas and monodispersas "this invention relates to a process for the preparation of biodegradable microspheres monodispersas who understand the steps of: (a) preparation of a synthetic latex emulsions Will that comprises at least a polymer phase and at least one aqueous phase.And the reason of the viscosity between the polymer phase and the dispersed aqueous phase continuous is between 0.1 and 10; (b) submission of the emulsion obtained a laminar shear controlled; (c) removing the solvent from the polymer phase; and (d) isolation of the microspheres obtained S. the present invention refers also to the use of the microspheres so prepared.
