Abstract

A resorbable polymer suitable for producing a medical product, comprising a triblock terpolymer with a structure ABA formed from a biodegradable hard segment A and a biodegradable soft segment B, has as the soft segment a statistical terpolymer with a completely amorphous structure. A process for its production comprises chemically reacting the hard segment monomer with hydroxy terminal groups of the soft segment B. The resorbable medical product produced from the triblock terpolymer can be a textile fabric, produced from multifilaments, a film, membrane or an injection molding.
