1. A process for polymerization of a monomer in a loop polymerization reactor controlled by a reaction rate controller program, comprising:
continuously and periodically obtaining polymerization results comprising at least melt index (MI), production rate and ash content on the polymerized monomer;
the reaction rate controller program (RRC):
determining whether each of the polymerization results is within predetermined target ranges for those results;
storing recently obtained polymerization results in a computer readable database stored within the RRC, and averaging the recently obtained results with previously stored results; and
when at least one of the polymerization results is out-of-range with respect to its predetermined target range, modifying at least one reaction parameter set-point comprising monomer concentration, catalyst feed rate or reactor temperature, and controlling associated hardware for modifying reaction parameter set-point(s) to drive any out-of-range polymerization result(s) toward the predetermined target range for that result.
