Webinteraction parameter w. This unitless quantity was origin-ally introduced by P. J. Flory [1] and M. L. Huggins [2] as an exchange interaction parameter in their lattice model of polymer solutions. In their definition, the quantity kTw (k is the Boltzmann constant; T, the absolute temperature) is the average change in energy when a solvent ... WebDec 1, 2002 · The Flory–Huggins model in terms of activity coefficients is, for a binary system, written as: (4) ln γ 1 = ln φ 1 x 1 +1− φ 1 x 1 +χ 12 φ 2 2 where φ and x are the volume fractions and mole fractions, respectively, and χ is the composition-independent Flory–Huggins interaction parameter. Usually, the Flory–Huggins model is based ...

Here, we compare descriptions of the swelling curves of such microgels using series expansions of the Flory–Huggins parameter $$\\chi$$ χ … WebThe interaction parameter (χ), related to the polymer and solvent solubility parameters in the Flory–Huggins theory, describes the polymer-solvent compatibility. In situ SE was used to measure the degree of polymer swelling in various solvent vapor environments, to determine χ for the solvent-PSS-H system. fishing green lake wisconsin
