Abstract: The molecular weights (Mw and Mn) and polydispersity (Mw/Mn) of a polymer have significant impact on the final product properties and processability of materials made out of it. This invention provides a method for on-line prediction of polymer properties. In a continuous polymerization reactor in which an irreversible polymerization reaction occurs, sensors provide axial temperature and pressure profile in the reactor as well as monomer flow rates and concentration for determining Mw, Mn and polydispersity. Based on a non-Newtonian fluid mechanics analysis, differential influx analysis of a side stream incorporation and determination of the moments of the molecular weight distribution via a Newton-Raphson algorithm, the model calculates an axial polymer properties profile.On-line real time "analytical measurement" of polymer properties is used to alert the operator of unusual reactor problems, to optimize reactor operation during shut-down and start-up or rate changes. This allows correlation of polymer properties to product performance in downstream processes.
