摘要: Functional poly(ester-anhydride) microspheres were prepared using emulsion solvent evaporation (ESE) and phase inversion methods (PIM). The poly(ester-anhydride)s obtained by polycondensation of sebacic acid (SBA) oligo(3-allyloxy-1,2-propylene succinate) terminated with carboxyl groups (OSAGE). effects various parameters, including: polymer emulsifier concentrations, stirring speed molecular weight polyvinyl alcohol (PVA) used as on size, size distribution morphology ESE technique examined. was in the range 2–30 µm depended mainly rate formulation process, well concentration solution used. Molecular PVA, its aqueous phase, significantly influenced tendency to agglomeration microparticles formed, but only slightly changed microspheres. present study demonstrated that method can be useful fo...
