Abstract
The possibility of utilizing cloud point titrations for obtaining theta-cosolvent compositions for PVC solutions was examined for a range of THF—nonsolvent systems. Hansen's1–3 “radii of solubility spheres” were calculated for the various solvents and cosolvent solutions and compared with the observed solubility behavior. The application of theta-cosolvent solutions for simplifying the determination of the number-average molecular weight was also examined.
