Patent ID: 6924652

Claim:
A method for controlling an optimal degree of vulcanization for a vulcanized sample in real time and determining an optimal content of each constituent ingredient of a polymer composition for vulcanization, the method comprising: (a) measuring an impedance during an actual vulcanization process in a frequency range of 1 Hz to 10 kHz so as to evaluate the properties of the vulcanized sample; (b) analyzing the measured impedance data for fitting to determine various parameters; (c) determining a polymer resistance Rp, among the parameters, with respect to an elapsed time of the vulcanization process; (d) determining, as an optimal end point of vulcanization, a time point at which the increasing rate of the polymer resistance Rp rapidly slows down; and (e) determining the optimal content of each constituent ingredient of the composition for vulcanization when the polymer resistance Rp of the sample completely vulcanized is at its minimum.
