The Flory‐Huggins interaction χ and the closely related heat of mixing parameter B were determined for several nitrocellulose‐nitrate ester systems. A micromethod which permitted the use of a simplified version of the Flory equation was successful in evaluating the effects of two series of nitrate ester diluents with nitrocellulose. A distinct difference exists between the effect of αω‐ and α,β‐substituted diluents as shown by the χ and B parameters. Generally, the terminally substituted nitrate esters appear to be the better solvents.
