Summary of Polymer Chain Statistics and Dimensions

where: <r²>_o is called the "unperturbed" dimension

Behavior Under Various Solvent Conditions

Good Solvent" (i.e., excluded volume limit)

"

"Theta" or "Ideal" or "Unperturbed" (i.e., cancellation of nonidealities)

"Poor" or "Globule" Conditions (i.e., chain collapses on itself)
