The molecular weight distribution problem and reptation mixing rules

Molecular Weight Dependent Kernels in Generalized Mixing Rules

In this paper, a model is proposed for the kernel in the generalized mixing rule recently formulated by Anderssen and Mead (1998). In order to derive such a model, it is necessary to take account of the rheological significance of the kernel in terms of the relaxation behaviour of the individual polymers involved. This leads naturally to consider a way how additional physical effects, which dep...

Rheological Method for Determining Molecular Weight and Molecular Weight Distribution

The molecular-weight distribution of glycosaminoglycans.

1. A rapid and sensitive method for the accurate estimation of the molecular-weight distribution of keratan sulphate and chondroitin sulphate isolated from adult bovine nasal septum and intervertebral disc is described. The method utilizes gel chromatography of reductively labelled glycosaminoglycan and end-group estimation of number-average molecular weight for each fraction across the peak of...
