<p>The present invention concerns a process to monitor formation of a polymer having internal mechanical constrain wherein acoustic emission generated by said polymer formation is detected by one or more acoustic sensors. The present invention also relates to a device to carry-out the above process said device comprising :
€¢ one or more acoustic sensors attached to a piece of equipment turning the acoustic emission to an electrical or digital signal,
€¢ means for filtering said signal in order to discriminate against usual noise of said equipment and connected to means to display the frequency, the power in Decibels (dB) and amplitude,
€¢ means to compare said measurements to previous typical recordings from said acoustic sensor attached to said piece of equipment : one recording when there is formation of a polymer having internal mechanical constrain and another one when there is no formation of a polymer having internal mechanical constrain. The present invention is particularly useful for monotoring the popcorn polymers made from butadiene or isoprene.</p> |
