Description
Summary:The limiting strength and relaxation (stress relaxation and creep) properties of films based on copolyphenylquinoxaline naphthoylene benzimidazole of regular structure have been studied. A new criterion of solubility is employed to analyse the effect of the quality of the dissolving medium in obtaining the films on their mechanical properties and its is shown that they may change within wide limits for a polymer of the same chemical structure.
