Kf. Arndt et al., Scattering function of non-substituted cellulose dissolved in N-methylmorpholine-N-oxide-monohydrate, MACRO SYMP, 162, 2000, pp. 109-119
The solution state of non-substituted cellulose dissolved in the monohydrat
e of N-methylmorpholine-N-oxide was investigated by static light scattering
measurements. Molecular masses of the cellulose of several millions g/mol
were observed. The overall particle scattering function can be separated in
to two individually scattering contributions. Two models could explain such
a behaviour. First, the results reflect a bimodal distribution of the diss
olved polymer consisting of large and small aggregates. The second attempt
at an explanation is based on the model of a fringed micelle. The light sca
ttering on different parts of the micelles, the core and the fringes causes
the discussed scattering function. The angular dependence of the scatterin
g intensity is simulated by superposition of particle scattering functions
and parameter fit.
