INDEX macroscopic stress

The smart response capability of polysaccharides upon application of stress allows polar and apolar domains to easily form or disintegrate due to variation of the order/disorder ratio at the molecular level. This finally results in variation of specific crystallinity index or crystalline/amorphous ratio at the macroscopic level. Significant variation of interactive properties may even be achieved by minor variation of branching characteristics, which changes surface/volume ratio and, hence, preferences for inter- or intramolecular stabilization. Additionally, a rather effective response option is variation of relative percentages of molar and mass fractions by limited degradation/ reorganization or precipitation/dissolution transition. 

An analysis of the previously defined function B(T) for dilute solutions of polymers in polar solvents may be helpful for the understanding of the interaction between polymer and these solvents.33 Applying Frohlich s theory, in which deformation polarization is treated macroscopically, we consider the solution as a cpntinuous medium containing polar units. The dielectric constant of the continuous medium is taken as equal to the square of the refractive index of the solution n0. This value is very close to that of the solvent. Each polar unit is represented as a sphere of dielectric constant 0a, haying a point dipole located at its center. It must be stressed that polar units may be either whole...
