Webfor an ideal chain. Thus, the only difference in a Flory good-solvent chain and an ideal chain is ∆U. We can write down a virial expansion of U as U = VkBT(βη2 +γη3 +δη4 +···) (3) where β, γ, δ ··· are the second, third, fourth ··· virial coefficients which are fully determined WebThe Flory–Huggins theory plays an important role in assessing the mutual miscibility of the polymer and the plasticizer. The so-called Flory–Huggins parameter of mutual interaction is the criterion defining the miscibility of PVC with plasticizers. It allows for a quantification of the affinity of the plasticizer with the polymer.

WebMay 16, 2011 · This chapter reviews the elementary statistical properties of a single polymer chain in solvents of different nature. Starting with the ideal random coil conformation and its tension–elongation relation, the excluded-volume effect is introduced to study the swelling and collapse of a random coil.
