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.

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.
