摘要： Embodiments of the present invention relate to measuring and controlling static in a gas phase reactor polymerization. In particular, embodiments relate to monitoring carryover static in an entrainment zone during gas phas e polymerization to determine the onset of reactor discontinuity events such a s chunking and sheeting. Embodiments also relate to monitoring carryover stati c to determine the need for effective additions of continuity additives that minimize reactor static activity and thereby preventing discontinuity events .
