... The structures of liquid crystalline copolymers based on HBA and HNA have been studied by several authors [8–10]. The X-ray patterns of a copolymer fiber show strong equatorial and non-periodic meridian reflections. For the 75/25 HBA/HNA copolymer, the structure obtained using an as-spun copolymer i ...
