Porous microspheres of polyester±polyether block copolymer based on polycaprolactone/ polylactide/poly(ethylene oxide) (PCEL) were prepared by an emulsi®cation±solvent evaporation technique. The effect of hydrophilicity/hydrophobicity of the polymer on the morphology of the PCEL microspheres was stu
