This part of GB/T 33061 specifies the general principles of the test method for the dynamic rheological properties of polymer melts by using a parallel plate oscillatory rheometer. Its typical angular frequency range is 0.01 rad/s~100 rad/s, and angular frequencies outside this range can also be used (see Note 1). Used to determine the following dynamic rheological parameters: complex shear viscosity η*, dynamic shear viscosity η′, heterogeneous part of complex shear viscosity η″, complex shear modulus G*, shear loss modulus G " and the shear storage modulus G'. This section applies to the determination of the typical value of the complex shear viscosity is not less than 10 MPa ? s (see Note 2).
