These materials have the general structure shown in Figure 20.11 and are prepared by reaction of bisphenol A with iso- and/or terephthalic acid and a carbonate group donor (e.g. phosgene or diphenyl carbonate). 

Another structure with a 10-7r-electron conjugated system is bicyclo[6.2.0]deca-1,3,5,7,9-pentaene. The crystal structure of the 9,10-diphenyl derivative (Fig. 9.6) shows the conjugated system to be nearly planar. " ... 

There are some reports proposing that structures not present in the aqueous resole are formed during cure, to include 2,2-diphenyl ethanol and 1,1,3,3-tetraphenyl propane crosslink structures [132,158,159]. However, these have not...
