Abstract

A novel approach which accounts for the independent contributions to the specific diamagnetic susceptibility (χm) of the amorphous and crystalline phases in, both, the solid and the liquid state of a series of low density polyethylenes (PE) is reported. The dependence of diamagnetism, for each phase contribution, on crystallinity is derived. The much larger rate of increase found for the diamagnetic contribution of the amorphous regions to χm is in accordance with the major influence of defects, perturbing the packing of chain segments rejected from the crystals. A parallel discussion for the liquid state favours the occurrence of a local mesomorphic state above the melting point.
