Molecular design of a speciality polyester for potential use as a fast-absorbable monofilament surgical suture

This paper describes the molecular design of a speciality polyester for use as a fast-absorbable monofilament surgical suture. In the surgical context, "fast-absorbable" means tensile strength loss within a period of 10-14 days, the minimum period required for secure wound approximation, a...
