A Rheokinetics Approach to Determine Poly(Furfuryl Alcohol) Resin Shelf Life

Shelf life of poly(furfuryl alcohol) (PFA) resin at ambient conditions was determined by model fitting on rheokinetics data of PFA cure profile at higher temperatures. Isothermal cure kinetics at higher temperatures was studied by tracing the variations in complex viscosity of PFA resin samples vs. time. Two mathematical models were fitted on the experimental data and the obtained kinetic constants according to the two models were extrapolated to 25°C and corresponding equations at ambient temperature were simulated. A profile of viscosity changes as a function of time under normal storage conditions was presented and shelf life of the resin was determined PFA storage at 25°C. The results were validated using experimental results obtained from real-time tests on the same PFA resin
