摘要：

A structural and magnetic study of a copper-containing nematic polyester has been carried out. X-ray diffraction, magnetization, and EPR experiments on samples with different thermal histories have been performed. In powdered samples, changes in magnetic properties are related to thermally induced structural modifications. A detailed study of a nematic melt-drawn fiber was made. The fiber displayed a large nematic order parameter and a parallel alignment of the copper coordination planes with the stretching direction.
