Solution viscosity of polystyrene at conditions applicable to commercial manufacturing processes

Literature data and previously unpublished results were correlated for polystyrene solutions at temperatures, compositions, and shear rates applicable to commercial practice. The primary correlation is for the zero shear viscosity and includes 222 points within the following ranges: temperature, T/k, 293-513; weight-average molecular weight, M r , 52000-381000; polydispesity, P d , 1.01-5.2; weight fraction of polymer, W p , 0.06-1.0
