1. A method for monitoring a resin-producing polymerization reaction in a fluidized bed reactor system wherein the reactor system comprises a fluidized bed reactor and a product discharge vessel into which polymer product is discharged from the fluidized bed reactor, the method including the steps of:

  • (a) monitoring at least one reaction parameter of the reaction to generate in on-line fashion time-domain reaction parameter data, wherein the reaction parameter data includes static data and the monitoring includes measuring product chamber static data indicative of static charge transferred from the polymer product to the product discharge vessel during each of a sequence of intervals; and

    (b) determining mathematical entropy of each of at least two subsets of the reaction parameter data, each of said subsets of the reaction parameter data including data values in a different one of a sequence of different time intervals.
