Mutual Diffusion Coefficient and Vapor−Liquid Equilibrium Data for the System Polyisobutylene + Toluene
Résumé
Vapor-liquid equilibria and mutual diffusion coefficients have been measured for polyisobutylene+toluene system from 5 0 C to 65 0 C by gravimetry. Empirical relations have been determined for the Flory interaction parameter and for mutual diffusion coefficients. They show a very good agreement with experimental data and can be accurately used for simulation or other purpose, as long as they are restricted to the concentration and temperature ranges covered by our study.
