 PGS is synthesized by a polycondensation reaction of glycerol and sebacic acid, which can be melt processed or solvent processed into the desired shape.PGS has a Young's modulus of 0.28 MPa and an ultimate tensile strength greater than 0.5 MPa.Peripheral nerve has a Young's modulus of approximately 0.45 MPa, which is very close to that of PGS.
