TIT# Data analysis of 2D-SAXS Patterns with Fibre Symmetry from Some Elastomers AUT# Stribeck, N. SOU# Fibre Diffraction Rev. (1997), 6, 20-24 LOC# xv032 @selbst.ftx CLA# COM# APP# MAT# ABS# Using a dedicated programming tool for scientific use (pv-wave), a program is being developed in order to analyse quantitatively 2D SAXS patterns with fiber symmetry. As the first detectors for synchrotron radiation have become available which allow the recording of high resolution patterns with a good signal-to-noise ratio in a short time, there is urgent need for such evaluation tools. Using data recorded during the straining of thermoplastic elastomers, the program and the underlying concepts are presented.
