The study of the electro-optical properties of liquid crystalline (LC) systems is an important topic in materials science due to the huge potential for their use. We investigated the electrooptical properties of comb-shaped LC polyacrylates with phenylbenzoate mesogenic fragments containing methyl or butyl terminal groups. The butyl-containing polymer is characterized by a complex reentrant polymorphism. Upon cooling in an electric field, both polymers samples display an unusual textural transition. Since this transition is observed regardless of the terminal group length, it was concluded that it is entirely determined by the structure of the mesogenic fragment.
