Abstract
A study was carried out of the tensile strength of plane-oriented amorphous and crystalline polymer films previously acted on by water and aqueous solutions of salts and organic acids. The dependence of strength on the time of exposure to the action of liquids was found to be extremal in character. X-ray diffraction analysis and optical measurements established that the increase in strength is accompanied by an increase in the optical anisotropy of polymers and is associated with supplementary spontaneous orientation of a part of their structural elements.
