Optimization of glass transition temperature and pot life of epoxy blends using Response Surface Methodology (RSM)
The aim of this work was to improve the processability of triglycidyl-p-aminophenol (TGPAP) epoxy resin. To achieve this improvement, a diluent, the diglycidyl ether of bisphenol F (DGEBF or BPF), was added to TGPAP, and the blended epoxy was then cured with 4, 40 -diaminodiphenyl sulfones (DDS)....

| description | The aim of this work was to improve the processability of triglycidyl-p-aminophenol (TGPAP) epoxy resin. To achieve this improvement, a diluent, the diglycidyl ether of bisphenol F (DGEBF
or BPF), was added to TGPAP, and the blended epoxy was then cured with 4, 40
-diaminodiphenyl
sulfones (DDS). A response surface methodology (RSM) was used, with the target response being
to achieve a blended resin with a high glass transition temperature (Tg) and maximum pot life (or
processing window, PW). Characterization through dynamic mechanical thermal analysis (DMTA)
and using a rheometer indicated that the optimum formulation was obtained at 55.6 wt.% of BPF
and a stoichiometric ratio of 0.60. Both values were predicted to give Tg at 180 ◦C and a processing
window of up to 136.1 min. The predicted values were verified, with the obtained Tg and processing
window (PW) being 181.2 ± 0.8 ◦C and 140 min, respectively, which is close to the values predicted
using the RSM. |
