Immiscible blends of thermotropic liquid crystalline polymers (TLCP) and a flexible polymer matrix show viscosity reductions and extensive fiber formation under certain flow conditions. Here we study these phenomena by directly examining the TLCP component's molecular orientation and the dispersed p
