BEZWADA BIOMEDICAL LLC Poly(dioxanone), viscosity 1.5 to 2.2 dl/g, 5.0 GM
Poly(p-dioxanone) is prepared via ring-opening polymerization of p-dioxanone. It is the base material for the monofilament synthetic suture PDS, marketed by Ethicon Inc. Poly(p-dioxanone) has a low melting temperature of approximately 110 to 120oC and exhibits a low glass transition temperature of approximately -5 to -15oC. This material has crystallinity of approximately 30-45%. It is the low glass transition temperature of poly(p-dioxanone) and its ability to be crystallized, coupled with its biocompatibility, which resulted in its application as a monofilament suture and other absorbable devices that can be flexed without breaking. The PDS suture retains 50% of its initial breaking strength after 3 weeks and is absorbed within 6 months, providing an advantage over Dexon or other products for slow-healing wounds. The polymer is used in medical devices and 3 D printing.
