A common error is to confuse the GPC distribution with the weight distribution. The response of a refractive index detector is proportional to the mass of polymer. The GPC elution volume (V) typically scales according to the logarithm of the degree of polymerization (or the logarithm of the molecular... [Pg.241]

All unfractionated cellulose triacetate samples and high molecular weight fractions showed a shoulder on the high molecular weight side of the GPC distribution. Material Isolated from this region was found to be highly enriched in mannose and xylose, attributed to the presence of a hemicellu-lose derivative. Cellulose triacetate from cotton linters did not show this behavior. [Pg.365]

Nobile and Cocchini [34] then used the step relaxation function in the double reptation integral, together with the Gex molecular weight distribution, to calculate the parameters of the latter for several polymers. In order to obtain G(f) from dynamic data, they approximated the former by a series of linear segments. Comparing their results with GPC distributions they found... [Pg.270]
