Fließverhalten und molekulare struktur von polymeren und ihren lösungen eine systematik quantitativer beziehungen

For viscosities at low and high shear forces τ, critical shear forces τ_w of the structural viscosity, YOUNG moduli in the rubbery region of the relaxation behaviour of entangled polymers, concentrations φ⁺ above which entanglements form a network, and intrinsic viscosities one may formulate quantitative relations to structural parameters (molecularweights M and their distribution, concentration, chemical nature, especially the molar volume V_g of the structural unit) or at least qualitative ones (different types of branching, distribution of chemical composition, sequences of like structural units, heterogeneity as a consequence of phase separation, crystallinity). Several new quantitative relations are presented. These and the known relations are connected to each other much more, than has been formulated up to now. They lead to some laws for the normal behaviour of mixtures and solutions which have not been detected phenomenologically.
