Studies of the Structure of Blends Containing Two Liquid Crystal Polymers

Blends in which both of the component materials are capable of forming liquid crystalline phases are considered in the present work. Solid-state characterization data are presented that suggest that chemical reaction is not a dominant event when two such materials are blended in the melt. Also, ideas of small-molecule liquid crystal mixing are shown to be not applicable to describe the behavior of this system. A formalism for describing blends of liquid crystal polymers, based on Windle's sequence matching arguments, is proposed.
