Beschreibung
Zusammenfassung:	A process simulator and modeling methodology employs instantaneous property measures. The instantaneous measures of various polymer properties are tracked throughout the subject polymer manufacturing system and used to calculate respective property distribution functions. For example, property distributions of composition, molecular weight, stereoregularity and long chain branching are calculated, tracked in time and location throughout the manufacturing system, and used to model the polymer manufacturing system and polymerization process performed by the system. More specifically, the present invention calculates full distribution of polymer properties from the instantaneous property measures and tracked instantaneous property distributions. This enables accurate and computationally efficient modeling of the polymerization process and manufacturing system for carrying out the same. The present invention method and apparatus thus enables modeling of polymer manufacturing systems (a) operating under transient or steady-state conditions, using free radicals or catalysts with a plurality of active center types, and having reactor types of CSTR, PFTR or any combinations thereof operating in batch, semi-batch or continuous operation, and (b) for carrying out polymerization processes including solution, slurry, gas phase, suspension and emulsion polymerizations.
