Polyoxyethylene Diamine Modification of Poly(amide-imide)-polyethylene Glycol Exhibits Excellent Hydrophilicity, Degradability, and Biocompatibility.

The degradation data shows ( Figure 5 B) that the weight loss rate of the material in the initial stage of degradation displayed a decreasing trend, which means that the mass of the material did not decrease at the initial stage of degradation, but increased, and tended to degrade normally in the later stage of degradation, which may be related to the material’s adsorption of crystal water in PBS.
