Radiation Sterilizable Bioabsorbable Monofilaments Based on Copolymers of Glycolide and 1, 5-Dioxepan-2-One

Copolymers of glycolide (GLY) and 1,5-dioxepan-2-one (DXO) were prepared with small amounts of a partially aromatic polyester (PG-2) of 1,4-phenylene- bis-oxyacetic acid and ethylene glycol incorporated in the final copolymeric macromolecular chain. The copolymers were extruded, drawn, and annealed...

Description
Summary:Copolymers of glycolide (GLY) and 1,5-dioxepan-2-one (DXO) were prepared with small amounts of a partially aromatic polyester (PG-2) of 1,4-phenylene- bis-oxyacetic acid and ethylene glycol incorporated in the final copolymeric macromolecular chain. The copolymers were extruded, drawn, and annealed into monofilaments which exhibited good tensile properties. When the monofilaments were sterilized by gamma radiation at 2.5 Mrads, the resultant fibers retained higher tensile strengths as compared to the fully aliphatic con trol fibers.
