We show through extensive rheological studies that Side‐Chain Liquid Crystalline Polymer melts reveal an unexpected and surprising strong elasticity instead of a classical flow behaviour. Neutron Scattering experiments demonstrate that this elastic plateau cannot be correlated to the long range order of the nematic phase.
