Reaction Conditions

Reaction Steps

To a 1 L glass reaction vessel, methylhydroquinone (1.07 moles, 133.14 g), bisphenol-A (0.03 moles, 6.28 g) and diphenyl carbonate (1.19 moles, 254.50 g) were added. The system was purged and backfilled with nitrogen three times. After heating the system to about 180° C., the system underwent a modified series of the 11 segments described in Table 1 where Segments 7 and 9 were shortened to about 5 minutes and the temperature for Segment 11 was 310° C. After a total of almost 3 hours, the polymer was stranded to give about 124 g and about 132 g each for two batches.
