| Abstract: | The short range ordering in molten polyethylene has been investigated by radial distribution function (RDF) methods. The intramolecular distances resolved are consistent with the presence of gauche conformations, whilst no long trans sequences are resolved. Broad peaks at ～5, 10 and 15 Å are attributed to intermolecular ordering, which is greater than that observed in glassy amorphous polymers. The results are not inconsistent with the polymer chains adopting a random coil configuration over distances greater than . |
