1. In a digital processor, a method for modeling a polymerization process carried out in a polymer manufacturing system formed of plural reactors and ancillary equipment, the method comprising the steps of:

  • receiving indications of reactor type and polymers involved in the polymerization process, each polymer having at least one molecular property;

    determining instantaneous property measures of the molecular properties of the polymers;

    generating and tracking respective instantaneous property distributions of the molecular properties from the determined instantaneous property measures;

    from the instantaneous property distributions, calculating full distributions of the molecular properties at any location in the manufacturing system;

    using the calculated full property distributions, forming and reporting a model of the polymerization process such that the polymer manufacturing system is modeled; and

    the method being capable of modeling both linear and non-linear polymerization processes.
