Abstract
Absorbable, segmented copolymers of aliphatic polyesters based on lactone monomers lactide, and p-dioxanone are described. The segmented copolymers exhibit a broad range of properties, especially high strength and long elongations. This unique elastomeric behavior makes the copolymers of the present invention useful in a variety of medical device applications, especially adhesion prevention barriers and hemostatic devices.
