FIELD: physics.
SUBSTANCE: invention can be used during the production of high molecular weight compounds, and also for forecasting change in the physical properties of polymers during different operating conditions. The essence of the device lies in that, the test sample of the polymer system of density ρ is put in the reactive type primary detector. The sample is heated under linear temperature T increase at the rate of 
measured and recorded on its clamps for a period of time Δt is the stress of the thermal electrical fluctuations u(t). The maximum value of the mean square 
of the stress of electrical fluctuation is determined, which corresponds to the glass transition temperature Tα, at this temperature the value of dielectric permeability is determined without action on the tested sample by an external electromagnetic field ε'f, the stiffness coefficient σ value is calculated, the activation energy Wα and time for molecular relaxation τ0α, as per the obtained data the modulus of elasticity in tension is calculated using the given formula.
EFFECT: ensures an increase in the information content of nondestructive and energetically non disturbing determination of the modulus of elasticity in tension of elastomers, in a high elasticity state.
