“…The corresponding B 23 values were 2.4 and 1.5 cal/cm 3 , respectively. This agreed with prior conclusions43, 44 that the former system was less compatible than the latter. Because the solubility parameter of NBR34 was closer to that of PVC than that of NBR28, the order of compatibility also agreed with the prediction of the solubility parameter method.…”

ABSTRACT:The solubility parameter method was applied to an analysis of the solution thermodynamic data of several solutes (probes) in polymers obtained by inverse gas chromatography. Experimental data previously reported by different authors were analyzed. The polymers used as the stationary phases were poly(vinyl chloride) (PVC), two nitrile rubbers (NBRs), and PVC/NBR blends. From the retention volumes of the probes, the Flory-Huggins interaction parameters at infinite dilution were calculated. The interaction parameters, in turn, were related to the solubility parameters of the solutes and stationary phases. With a series of probes, the solubility parameters of PVC and NBRs were determined. Differences existed between the experimental values of the size-corrected free energies of solutions and the values calculated with solubility parameters. The differences were generally negative values. When these differences obtained from two NBR rubbers were plotted versus PVC, a correlation was found. Methods for obtaining the interaction parameters of polymer blends were examined. A modified plotting method gave a linear line and an interaction parameter between two polymers consistent with the results of the solubility parameters.

The inverse gas chromatography method was extended to study the concentration dependent FloryHuggins interaction parameter between poly(vinyl chloride) (PVC) and plasticizers using literature data. For both PVC/ polyadipate and PVC/epoxidized soybean oil (ESO) systems, the miscibility was better at the high PVC end. The specific interaction between PVC and plasticizers was estimated from the difference between the experimental results and the enthalpies of mixing predicted by the solubility parameter model. The interaction was negative and skewed toward the high PVC end, and rendered the overall interaction parameter negative at high PVC compositions. Chemical potential was used to determine the phase composition of PVC/plasticizer mixtures.
