Résumé

This document specifies the general principles of a method for determining the dynamic rheological properties of polymer melts at angular frequencies typically in the range of 0,01 rad·s-1 to 100 rad·s-1 by means of an oscillatory rheometer with a parallel-plate or a cone-and-plate geometry. Angular frequencies outside this range can also be used (see Note 1). The method is used to determine values of the following dynamic rheological properties: complex shear viscosity η*, dynamic shear viscosity η', the out-of-phase component of the complex shear viscosity η”, complex shear modulus G*, shear loss modulus G”, and shear storage modulus G'. It is suitable for measuring complex shear viscosity values typically up to ~10 MPa·s (see Note 2).
