Abstract
Novel absorbable polymeric blends made from components wherein at least one of the components is synthesized using mixtures of mono- and di-functional initiators are disclosed. The blends have a first component that is a polylactide polymer or a copolymer of lactide and glycolide and a second component that is either poly(p-dioxanone) homopolymer, or a poly(p-dioxanone-co-glycolide) copolymer. The novel polymeric blends provide medical devices having dimensional stability. Also disclosed are novel absorbable medical devices made from these novel polymer blends, as well as novel methods of manufacture.
