Stress--Strain Curves of Glassy Poly(Arylate Sulphone) in Terms of Rubber Elasticity [Previously Titled: Description of the Stress--Strain Curves of Glassy Polyarylate Sulfone in the Framework of Rubber-Like Elasticity Concept.]

Previously abstracted from original as item 9109-C1-P-2202. The stress--strain dependences of polyblock polyarylate sulfone films prepared using various solvents have been interpreted in the 293-443K range using equations of the rubber-like elasticity theory. The concept of the molecular entanglements network allows for description of practically the entire stress--strain curve of this polymer in the glassy state, and explanation of the effect of the solvent type on the main parameters of mechanical properties.
