Abstract
The advances achieved by the method of electron microdiffraction in the study of the crystal structures of organic polymers with the aid of the transmission electron microscope are examined and the advantages and disadvantages of the method are analysed. It is shown that the diffraction studies on polymers in a transmission electron microscope not only supplement X-ray data but in many cases provide unique possibilities for structural analysis. The applied aspect of the structural studies of polymers is examined and methods are described for the preparation of the specimens and for protecting the polymeric object from the action of radiation.
