✦ Synopsis

The Flory-Huggins interaction x and the closely related heat of mixing parameter B were determined for several nitrocellulose-nitrate ester system. A micromethod which permitted the uae 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 a+-and a,p-substituted diluents as shown by the x and B parameters. Generally, the terminally substituted nitrate esters appear to be the better solvents.
