COPOLYMERE AUF BASIS VON CYCLISCHEN ESTERN UND IHRE VERWENDUNG ALS CHIRURGISCHE IMPLANTATE

The present invention relates to biodegradable copolymers derived from cyclic esters. In the copolymer, between 0.01 and 5 mol.% of the total cyclic ester-derived units are derived from TMC and between 99.99 and 95 mol.% of the total cyclic ester-derived units are derived from non-TMC cyclic esters....

Beschreibung
Zusammenfassung:	The present invention relates to biodegradable copolymers derived from cyclic esters. In the copolymer, between 0.01 and 5 mol.% of the total cyclic ester-derived units are derived from TMC and between 99.99 and 95 mol.% of the total cyclic ester-derived units are derived from non-TMC cyclic esters. Articles formed from the copolymers according to the invention are used in surgical procedures as for example in surgical implants. With this copolymer, it is possible to produce objects with an impact resistance of more than 11 kJ/m and a tensile strength of at least 51 MPa.
