摘要：

The introduction of lateral substituents and/or twisted biphenylylene units increase the solubility of aromatic para-linked polyesters. Two polyesters of this type of structure were characterized by gel permeation chromatography (GPC), low angle laser light scattering (LALLS) and viscometry. From the molecular weights and limiting viscosity numbers obtained by universal calibration and LALLS/viscometry the Mark-Houwink constants and persistence lengths were determined. The values of these parameters indicated that the polyesters can be described as wormlike chains in dilute solution.
