Various types of side‐chain liquid crystal polymers with ferroelectric, photoactive, thermochromic, hydrogen‐bonded, and ionized properties have been synthesized by many research groups, and their physicochemical properties and orientational behavior have been studied. These studies have established the relationship between the structure and the physicochemical properties. This chapter describes the design and synthesis of a conventional side‐chain liquid crystal polymer in which mesogenic side groups are attached to the polymer chains.
