| Application: | medical device |
| Application: | Polyglycolide (PGA) along with polylactide may be used to prepare a biodegradable copolymer to be used as implantations. Fabrication of biopolymer/carbon nanotube composite has been reported using PGA fiber as one of the constituents of the composite. Modified porous PGA scaffolds has been fabricated. |
| General description: | Biodegradable and biocompatible PGA could be potentially useful for bone regeneration. High molecular weight polyglycolide (PGA) can be prepared by ring opening polymerization of diglycolide in the presence of diphenyl bismuth bromide. |
| Packaging: | 1, 5, 10 g in glass bottle |
| Physical properties: | Biodegradable polymer |
| Preparation Note: | To achieve solubility in hexafluoroisopropanol, melt crystalline product and quench with liquid nitrogen to change material to amorphous form. |
