The polyetherurethane was composed by using poly (ethylene glycol) (PEG) and Lysine triisocyanate (LTI) and was provided at a high yield (90%). The polyetherurethane was characterized by thermal and mechanical properties. The thermal stability of the obtained polyetherurethane was measured by TGA, and the weight loss started at 290°C. The Young’s modulus of the obtained film taken from S-S curve was 63.2MPa. As a result of hydrolysis in phosphorus acid buffer solution (pH 8.4) as degradable examination, the obtained polyetherurethane was disintegrated into PEG and LTI.
