WebIn this paper, we explain the increased swelling of crosslinked polysaccharide microgels by the increase of sugar concentration using a modified Flory–Rehner theory. This theory is validated via the investigation of the swelling of dextran microgels in sugar solutions, which can be viewed as a model system for crosslinked starch in sugar ... Web3. The heat of mixing of polymer and solvent, which may be positive, negative, or zero. Usually it is slightly positive, opposing mixing. The FloryRehner equation may be written v2 13 2 - [ln (1 - v2 ) + v2 + c1v2 ] = V1 n v2 - 2 (9.92) where v2 is the volume fraction of polymer in the swollen mass, V1 is the molar volume of the solvent, and c1 ... http://netsu.org/j+/Jour_J/pdf/34/34-5-03.pdf highest tfsa interest rate
