Poly(N-acetyl-D-glucosamine) is soluble in hexafluoroisopropyl alcohol and hexafluoracetone sesquihydrate. The solutions formed may be wet or dry spun into filaments, or cast into films or solid articles, which may be used as absorbable surgical sutures, or other absorbable surgical elements. Poly(N-acetyl-D-glucosamine) is enzymatically degradable in living tissue, and is resistant to hydrolytic degradation, and, therefore, surgical elements thereof have good storage characteristics under a wide variety of conditions. |
