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 (Mw/Mn). 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.
