Abstract
Dissolution of an oxetane thermoplastic elastomer (binder) into ethyl acetate over the temperature range of 20-95 °C was studied in agitated vessels as a means for determining the recyclability of such TPE's using green solvents. The dissolution rates for the oxetane binder were well correlated with a quasi-stationary dissolution model. Equilibrium solubility values obtained from the mathematical model on the basis of the best fit to the dissolution data were found to be in good agreement with equilibrium solubilities obtained in independent experiments. Mass transfer coefficients were also obtained from the mathematical model on the basis of the best fit and the calculated activation energies were typical for diffusion controlled dissolution. These results indicate that dissolution and precipitation based recycling of the oxetane based formulation is indeed possible.
