Wholly aromatic, thermotropic liquid crystalline (LC) terpolyesters made from 6‐hydroxy‐2‐naphthoic acid (HNA) and 4,4′‐biphenol (BP) as key components have been prepared and evaluated for utility as high performance fiber precursors. The processability and fiber properties of a specific composition (1) made from both HNA and BP were compared with those of a more well‐known LC terpolyester made from p‐hydroxybenzoic acid, tere‐ and isophthalic acids and BP (Ekonol ® type). The advantages of polymer 1 and its high‐modulus fiber are described.
