Participants

Reaction Conditions

Reaction Steps

To a 1 L glass reaction vessel, methylhydroquinone (1.2 moles, 148.97 g) and diphenyl carbonate (1.29 moles, 277.63 g) were added. After heating the system to about 180° C., the system underwent Segments 1 through 5 and then skipped to Sement 11. After about 2 hours, the polymer crystallized at about 270° C. when about 90 wt % phenol had evolved. The solidified polymer could not be stranded.
