Rheological Equations of State of Linear Polymers and Their Mixtures

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

A rheological governing relation for the solutions and melts of linear polymers has been obtained based on the microstructural ideas of the dynamics of a polymer chain. A relation for taking into account the influence of the polydispersity of polymers on the properties of the mixture has been proposed and the components of the complex shear modulus — the elastic modulus and the loss modulus — have been calculated. The performed comparison of the theoretical results obtained and the experimental data for the mixtures of two samples of polystyrene in different ratios demonstrates satisfactory agreement of theory and experiment.
