Poly(dioxanone-co-glycolide)
Poly(dioxanone-co-glycolide) is a biodegradable copolymer synthesized from the ring-opening polymerization of p-dioxanone and glycolide. Due to the ester linkages found in the polymer backbone, these polymers are able to degrade via hydrolysis. With different degrees of aliphatic character, the ratio of the two monomers affects the rate of hydrolysis and therefore the rate of degradation. Other factors that affect the degradation of these materials could include the end application or post-polymerization processing methods. Uses: Poly(dioxanone-co-glycolide) is a biodegradable copolymer featuring the high strength of poly(dioxanone) and the flexibility of poly(glycolide) for use in biomedical research applications such as biomedical devices, drug delivery systems, and tissue engineering constructs. Group: Biodegradable polymers. Alternative Names: PDS-PGA, PDO-PGA. Mole weight: (C4H6O3)m(C4H4O4)n.
