Abstract
The morphology of semicrystalline polymeric materials(PETP) was studied by an etching technique and by isothermal inverse gas‐chromatography. Using these two techniques the same results for semicrystalline isotropic materials were obtained and these results wer found to depend only on the crystalline fraction. Isothermal inverse gas‐chromatography permits an evaluation of the macromolecular orientation while the etching technique shows the same behaviour both for isotropic and anisotropic materials.
