摘要：

Using data from different types of polypropylene (reactor-grade, peroxide-degraded and technical types), various correlations between parameters of the molar mass distribution, the storage and loss modulus and the steady shear viscosity are investigated. Most assumptions turn out to oversimplify the real, complex relations between molecular structure and rheological properties. Nevertheless they appear to be useful for first estimations in screening tests and production control.
