Title: Quantitative orientational analysis of a polymeric material (Kevlar{sup {reg_sign}} fibers) with x-ray microspectroscopy

It has previously been shown that x-ray linear dichroism microscopy can be utilized to image and determine orientation in a polymeric material at high spatial resolution. We have now expanded on this technique and extracted quantitative information about the orientation of specific functional groups in a polymeric system from submicron areas. This is accomplished by acquiring and analyzing spectral data sets rather than just images at specific energies. It has allowed us to compare the relative lateral orientation of various grades of Kevlar{sup {reg_sign}} fibers. {copyright} {ital 1996 American Institute of Physics.}
