Abstract

To analyze X-ray diffraction patterns obtained from polyimide films subjected to external influence (uniaxial tension and exposure at liquid helium temperature), radial distribution function (RDF) curves were constructed and the geometry of the 4,4'-oxydiphenylene-pyromellitimide monomer (PM) was calculated. From the RDF analysis, it follows that uniaxial tension of PM polymer films leads to a change in the geometry of the monomer, and exposure at low temperatures leads to mutual ordering of the polymer chains.
