The present invention relates to a biodegradable thermoplastic elastomer having the general formula A-B-A wherein each A is an amorphous polymer having a glass transition temperature (Tg) >40° C or a semi-crystalline polymer having a glass transition temperature (Tg) and/or melting temperature (Tm) >40° C B is a copolymer of -caprolactone (CL) and at least one additional monomer selected from the group consisting of L-lactic acid (LLA), trimethyl carbonate (TMC), and glycolic acid (GA), or B is different to A and is lactic-co-glycolic acid (LGA) and wherein the molar ratio of CL to the at least one additional monomer in the copolymer B is in the range between about 1:0.09 to about 1:1.
