  • Method for determining optimal degree of vulcanization and optimal content of constituent ingredient of composition for vulcanization in real time by impedance measurement and analysis
    Patent number: 6924652
    Abstract: The present invention relates to a method for evaluating the crosslink degree of a vulcanized sample in real time during a vulcanization process or diagnosing the electrical properties of the sample after the completion of the vulcanization process, and then determining an optimal vulcanization time and an optimal content of each constituent gradient of a composition for vulcanization that optimize the properties of the composition according to the vulcanization conditions, for the sake of improving the properties of the vulcanized sample prepared from a polymer by vulcanization at a high temperature.
