Formalized modeling of pyroelectric coefficient dependence on the kinematic viscosity during the first order phase transitions in oligodimethylsiloxanes.

The paper has analyzed the results of studies of PMS oligodimethylsiloxanes with the indices: 30, 40, 50, 100, 400, 1000. The results of experimental studies have served as the basis for the assumption of formation of a continuous crystalline field during crystallization of oligodimethylsiloxanes, which affects the increase of kinematic viscosity. An analytical dependence of the relative pyroelectric coefficient on the logarithm of kinematic viscosity has been obtained. The obtained ratio was used as the basis for determining the parameters of oligodimethylsiloxane crystallization process of in an inhomogeneous temperature field at temperatures of the first order phase transition.
