Four samples of polyethylene terephthalate (PET), with different thermal histories were investigated by radial distribution function (RDF) methods. Intramolecular distances in the polymer repeat unit were successfully attributed to peaks in the RDF p

An investigation of the molecular structure of amorphous aluminium phosphate, prepared from a recently discovered complex (AlPO4 · HCl · 4C2H5OH), has been carried out using radial distribution function (RDF) techniques. Studies were made on two sa

Measurements of the longitudinal acoustic (LA) Raman mode have been combined with small-angle x-ray scattering (SAXS) and nitric acid etching, followed by gel-permeation chromatography (GPC) to examine the morphology of bulk-crystallized linear polye

Interatomic and intermolecular ordering in amorphous polymers can be characterized by radial distribution functions (RDF) derived from radiation scattering measurements (X-rays, neutrons, etc.). The type of information which may be derived from RDF d

A microscopical technique has been used to determine rates of crystallization (devitrification) of some lead phosphate and potash lead phosphate glasses. The devitrification rate is viscosity dependent, and compositional effects were resolved from vi

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 re
