Chapter 3. Conformation, Solutions, and Molecular Weight

Solvents are frequently used during the polymerization process (Chapter 2), during fabrication (e.g., film casting, fiber formation, and coatings), and for determining molecular weights and molecular-weight distributions. Interactions between a poly-mer and solvent influence chain dimensions (i.e., conformations) and, more importantly, determine solvent activities. The measurement of osmotic pressure and scattered-light intensity from dilute polymer solutions—techniques based upon the principles of polymer-solution thermodynamics—are the primary methods used to determine number-average and weight-average molecular weights, respectively. Other solution-property techniques, such as the determination ...
