    • The invention pertains to a process for the manufacture cola medical implant, said process comprising: reacting a mixture of non functional, monofunctional, and bifunctional perfluoropolyethers comprising hydroxyl terminal groups, wherein the average functionality is of at least 1.97 [mixture (M)] with suitable reactants for producing a thermoplastic elastomer; moulding the so-obtained thermoplastic elastomer for yielding at least a part of the medical implant. It has been surprisingly found that by using a mixture of perfluoropolyethers having high functionality, it is advantageously possible to manufacture, by moulding thermoplastic elastomers therefrom, medical implants which exhibit improved biocompatibility and which are submitted to reduced chemicals extraction by biological fluids.
