Тезис

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.

The method is applicable for determining 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”, shear storage modulus G', phase angle δ, and loss factor tanδ. It is suitable for measuring complex shear viscosity values typically up to ~10 MPa s.

NOTE            The shear loss modulus G´´ is sometimes also called viscous shear modulus and the shear storage modulus G´ is sometimes also called elastic shear modulus.
