Inferring the Molecular Weight Distribution (MWD) of a polymer in solution from ultracentrifuge sedimentation equilibrium data has been a problem of major concern during the past decades. Recently, it has been shown that this problem is of itself mat

Inferring a relaxation spectrum from mechanical test data was approached as a mathematically ill‐posed or incorrectly formulated problem in the Tikhonov sense. A compound technique presented previously by the authors, which incorporates Tikhonov’

The dependence of the ultracentrifugal sedimentation coefficient s on the concentration has been derived directly from the theory of hydrodynamics for the case of very dilute solutions. The following general expression has been obtained: s = s0(1 −

The combined sedimentation and diffusion process of macromolecules in the centrifugal field was considered phenomenologically. For each dissolved particle a stochastic equation is estimated composed of two independent velocities: a diffusional and a

A purified and unfractionated sample of polybenzimidazole (PBI) in dimethylacetamide (DMAC) was subjected to equilibrium sedimentation in order to determine the molecular weight distribution (MWD). Since the solubility of PBI is very limited and Θ c
