Procedure
To a 1 L glass reaction vessel, methylhydroquinone (1.089 moles, 135.19 g), bisphenol-A (0.011 moles, 2.51 g) and diphenyl carbonate (1.19 moles, 254.50 g) were added. After heating the system to 180° C., the system underwent a modified series of the 11 segments shown in Table 1, where Segments 7 and 9 were shortened to about 5 minutes and the temperature for Sement 11 was 320° C. After a total of about 3-4 hours, the polymer was stranded to give about 92 g and about 104 g each for two batches. (GC analysis of the 1% BPA distillate: 80% phenol, 13% DPC and 1% MeHQ).
