ABS# The nanostructure deformation mechanism of a predrawn and annealed
     poly(ether ester) (PEE) thermoplastic elastomer comprising
     poly(butylene terephthalate)  as hard segments and poly(ethylene glycol)
     as soft segments of a wt ratio 57/43 was studied by means of synchrotron
     radiation. For this purpose a recently proposed method by Stribeck for
     extraction of the topological domain structure information contained
     in the small-angle X-ray scattering (SAXS) pattern was applied to
     patterns observed as a function of elongation of PEE when measured
     in the strained and in the relaxing state after straining. The SAXS
     fiber diagram as a whole was transformed into a three-dimensional
     chord distribution function (CDF) with fiber symmetry. Assignment of
     the observed peaks to the various structural characteristics of the PEE
     is suggested.
