Abstract:

The present invention discloses polymers of poly(p-dioxanone having an inherent viscosity in the range of from 2. 3 dL/g to about 8 dL/g, as determined at a concentration of 0. 1 g/dL in hexafluoroisopropanol at 25. degree. C. This invention also describes improved surgical devices and filaments made from poly(p-dioxanone) with an inherent viscosity in the range of from 2. 3 dL/g to about 8 dL/g, determined at a concentration of 0. 1 g/dL in hexafluoroisopropanol at 25. degree. C. Additionally, disclosed are processes for manufacturing poly(p-dioxanone) with an inherent viscosity in the range of from 2. 3 dL/g to about 8 dL/g, as determined at a concentration of 0. 1 g/dL in hexafluoroisopropanol at 25. degree. C. , as well as, processes for molding surgical articles and extruding surgical filaments from these polymers.
