Abstract:

A method for evaluating and controlling a mixing process for polymer-based compounds includes the steps: obtaining initial starting conditions and values for viscosity dependent parameters; increasing batch temperature by a differential amount; calculating mixing parameters such as batch temperature, dispersion, viscosity, and torque based upon fundamental kinetic, thermodynamic, and Theological models; determining whether an endpoint or end points of one or more mixing parameters has been achieved; and changing one or more conditions so as to achieve the desired endpoint(s).
