Abstract :
The authors describe multifunction test equipment for measuring and recording the dielectric spectrum, thermogram, and start-end gel-time of a high polymer specimen from liquid state to cure state. It is shown that the change of the polymer from liquid to solid during a complex cure process can be sensitively and accurately monitored by the dielectric analysis technique. A correlation of three parameters (viscosity, differential thermal analysis, and dielectric dissipation analysis) is established in order to supervise the technological measurement
