Van Gurp-Palmen-plot: a way to characterize polydispersity of linear polymers

摘要

This article is concerned with the so-called van Gurp-Palmen-plot which charts the phase angles vs the absolute values of the complex shear modulus from a rheological experiment. Its basic characteristic features are elucidated for polymers having a simple, i.e., a linear structure. A subsequent manuscript will then address more complicated topologies as present in long chain branched polymers.
