Abstract
Process to monitor unwanted formation of a polymer, having internal mechanical strain, wherein said formation of polymer generates acoustic emissions due to the sudden break of the polymer, wherein the number of said acoustic emissions increases over time when there is formation of said unwanted polymer formation, wherein said acoustic emissions is detected by a resonant piezo electric transducer having a resonant frequency centred on the second harmonic of said acoustic emission.
