Thenew condensed polymers were characterized by FTIR and UV. spectroscopy.The physical properties were measured, and the swelling % were studied withdifferent non solvents. The intrinsic viscosity was measured by Ostwald-viscometer,using DMF as a solvent The TGA and DTA were studied. The high softening pointswere measured for all condensed polymers which have higher than 240 OC. Thecontrolled release were studied in different pH values at 37 0C.The inserted moiety units of sulfonated aminoacids could enhanced thebiocompatibility, bioactivity and biodegradability properties for these preparedbiomaterials polymers, and the incorporation of aminoacids through backbone of thecondensed polymers.
