Abstract
A melt of a copolymer of 60% hydroxybenzoic acid and 40% ethylene terephthalate was subjected to a uniform magnetic field with B = 0.65 T at 300 °C. The structure and thermal expansion of the material was studied by x-ray diffraction and dilatometry. The magnetic field produced a highly oriented structure. Dilatometry revealed previously unreported relaxation transitions in this material.
