Abstract: Poly[bis(glycine ethyl ester)phosphazene] was blended with poly(d,l-lactide)(PLA) or poly(d,l-lactide-co-glycolide)(PLGA) in various mass fraction ratios by using solvent-mixing technique. The miscibility of these blends was studied by DSC, IRand contrast microscopy method. The results showed that PGPwas completely incompatible with PLA, but partially compatible with PLGAdue to the hydrogen bonding effect. Furthermore, the miscibility of PGP/PLGAwas improved with the increase of PLGAcontent in the blend.
