Non-extensivity of the chemical potential of polymer melts
J. P. Wittmer, A. Johner, A. Cavallo +3
Following Flory's ideality hypothesis the chemical potential of a test chain of length immersed into a dense solution of chemically identical polymers of length distribution P(…
Static Rouse Modes and Related Quantities: Corrections to Chain Ideality in Polymer Melts
H. Meyer, J. P. Wittmer, T. Kreer +4
Following the Flory ideality hypothesis intrachain and interchain excluded volume interactions are supposed to compensate each other in dense polymer systems. Multi-chain effects s…
Intramolecular long-range correlations in polymer melts: The segmental size distribution and its moments
J. P. Wittmer, P. Beckrich, H. Meyer +3
Presenting theoretical arguments and numerical results we demonstrate long-range intrachain correlations in concentrated solutions and melts of long flexible polymers which cause a…
Intramolecular Form Factor in Dense Polymer Systems: Systematic Deviations from the Debye formula
P. Beckrich, A. Johner, A. N. Semenov +3
We discuss theoretically and numerically the intramolecular form factor in dense polymer systems. Following Flory's ideality hypothesis, chains in the melt adopt Gaussian co…
Why polymer chains in a melt are not random walks
J. P. Wittmer, P. Beckrich, J. Johner +4
A cornerstone of modern polymer physics is the `Flory ideality hypothesis' which states that a chain in a polymer melt adopts `ideal' random-walk-like conformations. Here we revisi…
Are polymer melts "ideal"?
J. P. Wittmer, P. Beckrich, F. Crevel +4
It is commonly accepted that in concentrated solutions or melts high-molecular weight polymers display random-walk conformational properties without long-range correlations between…
