Cohesive energy densities of polymers from turbidimetric titrations

Abstract

Abstract Turbidimetric titrations have been made on polystyrene and poly‐ o ‐chlorostyrene in a series of solvents to deduce the solubility parameters of polymers from the Flory‐Huggins interaction parameter χ. The assigned solubility parameter for polystyrene agrees well with the reported values obtained from swelling measurements. Brief discussion of the exceptional behavior in the solvent powers of paraffins is given.
