Reaction Steps

To a 1 L glass reaction vessel, methylhydroquinone (1.045 moles, 129.73 g), bisphenol-A (0.055 moles, 12.56 g) and diphenyl carbonate (1.19 moles, 254.50 g) were added. The system was purged and backfilled with nitrogen three times. The system was heated to about 180° C. to melt the material and stirring began. The molten liquid was light yellow. The catalysts were added (TMAH followed by NaOH) via a syringe. The system underwent all 11 segments shown in Table 1. After about 3 hours, the polymer was stranded to give between 96-100 g of stranded polymer. Four batches were prepared.
