Self-consistent field theory extrapolation

As mentioned above, Edwards has used a self-consistent mean field theory to derive similar (though not identical) results to those obtained from scaling theory (Edwards, 1966 Edwards and Jeffers, 1979). One virtue of this approach is that the relationships were obtained from a single extrapolation formula which encompasses all concentrations from an infinitely dilute solution to bulk polymer. This means that a somewhat more intuitively acceptable picture of polymer solutions emerges, one where there is a gradual change from one concentration regime to another.
