Expansion of the Polymer Chain

Expansion of the Polymer Chain in a "good solvent"

(as opposed to the unexpanded polymer chain in the theta condition state)
If the solvent were a "poor solvent"then the word expansion would be replaced by the word contraction

[Hiementz-620]
[Sperling-76]

is the chain expansion factor [Hiementz-62]
is a constant
is an entropic factor
is temperature.
is the Flory Theta Temperature
It didn't specifically say what M was.
[Sperling-76]
where
- r is the end-to-end distance after expansion [Sperling-76]
- r(0) is the end-to-end distance in the theta condition [Sperling-76]
