ABS# A method for the analysis of equatorial scattering observed in SAXS
     patterns from strained two-phase poly(etherester)s is presented.  If the
     scattering can be attributed to an ensemble of rodlike domains, the mean
     rod diameter, the variance of the rod diameter distribution and other parameters
     of physical interest can be determined from the 2D chord distribution, which is
     related to a projection of the scattering pattern.  A series of patterns
     was recorded during straining of a polyetherester sample, Arnitel
     E2000/60, DSM, The Netherlands, in the synchrotron beam.  The material
     contains soft segments from poly(tetrahydrofuran) and hard segments of
     poly(butylene terephthalate).  With increasing elongation the mean rod
     diameter decreases and the relative width of the rod diameter distribution
     increases.  A saturation effect at elevated elongation is discussed in terms of
     strain induced crystallization of the soft segment blocks.
