Abstract
In 1926-1936, H. Staudinger clarified scientifically the existence of “macromolecules” in which low molecular substances link together by covalent bonds. In the experiments for this clarification, he used the solutions of cellulose and its derivatives. At the present time, it seems that many researchers in the field of cellulose science are interested in the structure and properties of the solid (crystalline) state of cellulose. However the investigations for the solution properties are also very important for characterizing cellulose as a “macromolecule”. This review provides an insight into the molecular characteristics of cellulose through its solution properties using light scattering and rheological methods.
