Laboratory-made samples of the polysaccharide xylinan, also called
acetan, were studied in aqueous solution at various ionic strengths
I (0.01 mol/L less than or equal to I less than or equal to 0.30
mol/L). The conditions for clarification (ultracentrifugation/membrane
filtration) were studied. The Zimm procedure was used to obtain the
average molar mass, the second virial coefficient, and the radius
of gyration. The interpretation of the angular dependence of scattered
Eight by fitting with ''Master Curves'' led to double-stranded wormlike
chains with persistence lengths between 90 and 120 nm. The ionic
strength had a strong effect on the thermodynamic second virial coefficient,
belt the overall structure remained unchanged. The ambiguity of the
light scattering data was dip cussed assuming alternatively a two-component
system instead of the wormlike chain model for the experimental scattering
curves. The two-component system can be ruled out on the basis of
model calculations. (C) 1996 John Wiley & Sons, Inc.
