Abstract
Various polyarylates from substituted hydroquinones (HQs) and substituted 1,2-bis(phenoxy)ethane-4,4′-dicarboxylic acids (PECs) or 4,4′-diphenyldicarboxylic acid (BB) were prepared. Thermal properties, orientation function of nematic domains (F value) and morphology of fibers and injection molded specimens of them were investigated. From these results, it is assumed that the stability of liquid crystallinity, rigidity of the polymer chain and F value are the important factors determining the modulus of fibers. On the other hand, the stability of liquid crystallinity, rigidity of the polymer chain and packing density of the polymer chain are assumed to be the influential factors to determine the modulus of injection molded specimens.
