Claim 5:
6. The polymer (F) according to claim 1, said polymer (F) having an elongation at break higher than 350%, as measured at 200° C. according to ASTM D 3307 standard method, and/or having a strain hardening index (SHI), measured according to the following equation:

SHI=[σ (200% strain)−σ (100% strain)]/[ε (200% strain)−σ (100% strain)]

wherein σ represents the applied stress on the material and ε represents the strain, wherein the stress and the strain were measured according to ASTM D 3307 standard method,
of at least 2.5 MPa at a temperature of 23° C.
