Web512 P. J. FLORY AND J. REHNER, JR. Equation (12) was used to find the curves shown in Fig. 1. The rate expression involving the acid chro mate ion is -d(Cr03)/dt = k(HCr04-) (CH3CHOHCH3) (H+)2. (6) The concentration of acid chromate ion can be calculated from the equilibrium expression where the parentheses indicate concentrations, WebThe swelling is shown as a ratio of volumes which is identical to 1/φ 2 which is the concentration of polymer in the swollen gel. Check your intuitions about the effect of the measure of "happiness" (the Flory-Huggins χ where 0.5 is starting to be unhappy) and the sizes of the polymer and solvent. The density of the polymer, ρ 2 play a minor ...

Rehner in the early 1940s. … 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 ...
