Zusammenfassung:	The present invention relates to specific DL-lactide-.epsilon.-caprolactone copolymers and the application of these polymers in the production of biodegradable medical applications. According to the present invention a polymeric material comprising poly(DL-lactide-co-.epsilon.-caprolactone) is provided, which is obtained by the copolymerization of DL-lactide and .epsilon.-caprolactone, having a lactide content of 51-75 mol%, most preferably of 62-69 mol%.The materials of the present invention have excellent mechanical properties and may be used to provide articles for medical application, in particular nerve guides. La présente invention concerne des copolymères spécifiques DL-lactide-e-caprolactone et l'application de ces polymères pour l'élaboration d'applications médicales biodégradables. Cette invention concerne un matériau polymère comprenant un bloc poly(DL-lactide-co-e-caprolactone), obtenu par copolymérisation de DL-lactide et de e-caprolactone, présentant une teneur en lactide de 51 à 75 moles pour cent, de préférence, de 62 à 69 moles pour cent. Les matériaux décrits dans cette invention présentent d'excellentes propriétés mécaniques et ils peuvent être utilisés pour obtenir des articles destinés à une application médicale, en particulier des guides de nerfs.
