A series of poly(ethylenepropylene)--poly(ethylethylene) (PEP--PEE) diblock copolymers, containing 55 vol.% PEP, and the corresponding PEP and PEE homopolymers have been investigated by dynamic mechanical spectroscopy. The ordered and disordered states are characterized by qualitatively different lo...
