Synthesis, characterization, and thermal properties of biodegradable polyetheresteramide-based polyurethane

In this paper, a new kind of biodegradable polyetheresteramide-based polyurethane (PEEA-U) copolymers were prepared by melt polymerization from ε-caprolactone, 6-aminocaproic acid, poly(ethylene glycol), and toluene diisocyanate. The obtained polymers were characterized by 1H NMR, FTIR, DSC, WAXD, a...

Zusammenfassung:In this paper, a new kind of biodegradable polyetheresteramide-based polyurethane (PEEA-U) copolymers were prepared by melt polymerization from ε-caprolactone, 6-aminocaproic acid, poly(ethylene glycol), and toluene diisocyanate. The obtained polymers were characterized by 1H NMR, FTIR, DSC, WAXD, and TGA/DTG. The water absorption, hydrolytic degradation, and alkaline degradation behavior of these copolymers were also studied in detail.
