FIELD: measurement technology. SUBSTANCE: characteristic feature of invention lies in measurement of temperature, energy of activation, of process of α- relaxation for specimen tested by dilatometric method. Tested material is placed into primary capacitor measurement converter. Mean-square value of current of thermal electric fluctuations, corresponding noise active conductance at temperature of test are measured and modulus of elasticity during tension is calculated by formula given in description of invention. EFFECT: enhanced informativity of nondestructive and energy undisturbed determination of modulus of elasticity during tension of polymers being in highly elastic state. 1 dwg
