In the high pressure of polymerization of ethylene homopolymer or copolymers conditions in the reactor may become unstable leading to the decomposition ("decomp") of the reaction mixture. Monitoring temperature excursions traveling through the reactor over close thermocouples (a roller) to detect changes in the mean temperature and the moving temperature front for a group of thermocouples detects conditions potentially leading to a decomp.
