Abstract: The observation of inversion walls and nematic schlieren textures with singularity of high strength in polymer samples is reported. The polymers are of the type with two-dimensional mesogenic units and flexible spacers in the main chain and all form a nematic liquid crystal phase above melting.

Key words: liquid crystal polymer, schlieren texture, disclination
