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. Alternative Names: PDS-PGA, PDO-PGA. Molecular formula: (C4H6O3)m(C4H4O4)n.
Poly(dioxanone-co-L-lactide)
Poly(dioxanone-co-L-lactide) is a biodegradable copolymer synthesized from the ring-opening polymerization of p-dioxanone and lactide. 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. Alternative Names: PDO-PLA, PDS-PLA. Molecular formula: (C4H6O3)m(C6H8O4)n.
