Abstract

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 absorbable polymer is suitable for the production of a surgical suture material, which is wholly or partly formed from the polymer.
