Cellulose derivatives play an important role in technical applications as stabilizers, thickeners, emulsifiers, and gelling and binding agents. However, it is difficult to improve the quality of existing applications and open up new areas due to the problems encountered in determining their molecular parameters. It has been shown that cellulose derivatives may contain varying amounts of aggregates or associations, which makes it difficult to establish structure-property relationships. Therefore this contribution intends to show that combining rheo-mechanical and rheo-optical devices can overcome these problems and thus provide qualitative and quantitative information on the viscoelastic properties and orientation under shear flow conditions. This information can then be used to establish new structure-property relationships.
