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.
WebSep 7, 2024 · Entropy of Multiple Polymer Chains. For \(N_P\) chains, we count growth of chains by adding beads one at a time to all growing chains simultaneously. 1) First bead. The number of ways for placing the \(1^{\text{st}}\) bead for all chains: 2) Place the second bead on all chains. We assume the solution is dilute and neglect collisions between … WebMy first degrees were in Physics, Mathematics and Biochemistry in my hometown of Adelaide, Australia, followed by an Honours degree in Biochemistry with Prof. John Wallace, studying insulin-like growth factors.
