Abstract
The electron-microscopic method was used to study the structure of unsaturated polyester films. The initial submicrocracks developing in the loaded films were studies by the low-angle x-ray diffraction method. It is shown that for these polymers a typical feature is the globular structure with a globule diameter of 103–3·103 Å, and the transverse dimension of the submicrocracks developing under the action of a load practically coincides with the globule diameter.
