A method for measuring a dynamic viscoelasticity of a particulate material uses, as a sample to be subjected to the dynamic viscoelasticity measurement, a sheet-shaped test piece in which the particulate material to be measured is attached to an adhesion layer formed on a heat-resistant sheet base material. With regard to the measurement conditions of the dynamic viscoelasticity measurement, the measurement temperature is within a predetermined temperature range of from -150 to 300°C, the heating rate is a constant rate ranging from 0.01 to 100 °C/minute, the measurement frequency is a constant frequency ranging from 0.01 to 100 Hz, and a sine wave control tensile mode is employed. When the particulate material is attached to the adhesion layer, the particulate material crushed in advance is sprinkled on one side of the adhesion layer and then the particulate material-sprinkled surface is squeegeed and/or air-blown. |
