CHEM 4214 Lecture Notes - Lecture 19: Repeat Unit, Kolmogorov Space, Inflection Point
Document Summary
Recap one phase black = binodal curve red = spinodal curve metastable unstable. Chem4212 polymers page 1 ex: 5x5 lattice: = repeat unit of polymer x = solvent monomers are linked together calculate delta gm for that. 1 repeat unit occupies 1 lattice site (so does one solvent moleculeeven though in reality, solvent molecule can be bigger or smaller) One repeat unit for flory-huggins theory might not be same as one repeat unit chemical structure. N = # repeat units (assuming that each monomer occupies one box) Chem4212 polymers page 2 volume fraction of polymer similarly, same effect happens to solvent (before, it was in small volume, and after mixing, it has larger volume to move around) Polymer (1) + polymer (2) look at previous picturenow imagine crosses are linked too. N1 = # repeat units for polymer 1. Chem4212 polymers page 3 we get tilt b/c n1 =!
