Simultaneous rheo-mechanical and rheo-optical characterization of viscoelastic polymer solutions with simple and complex structures

摘要

Intramolecular and intermolecular interactions are probably responsible for the complex range of properties found in polysaccharides. However, despite their wide fields of applications and intensive commercial exploitation - e.g. as flow enhancers, stabilizers, and agents for binding, suspending and thickening - there are still many unresolved questions concerning the relationships between solution structure, properties and effect (in relation to viscous and elastic properties, and in the presence of salts).
