<p>Liquid crystal polyester composed of at least one repeating unit of formula I, II, III, or IV, or combinations thereof display an improved balance of properties, including low melt viscosity, fast cycle time in molding, very low mold shrinkage, high tensile and/or flexural strength, solvent resistance, excellent barrier properties, low water absorption, low thermal expansion coefficient, excellent thermostability, and/or low flammability. The liquid crystal polyesters may be include repeating units derived from monomers such as 4-hydroxybenzoic acid, 2-hydroxy-6-naphthoic acid, terephthalic acid, isophthalic acid, or derivatives thereof.</p> |
