Reaction Steps
The epoxides can also be derived from mononuclear phenols, for example from resorcinol, pyrocatechol or hydroquinone; or they are based on polynuclear phenols such as on 4,4′-dihydroxybiphenyl, bis(4-hydroxyphenyl)methane, 2,2-bis(4-hydroxyphenyl)propane, 2,2-bis-(3,5-dibromo-4-hydroxyphenyl)propane, 4,4′-dihydroxydiphenylsulfone, 9,9′-bis(4-hydroxy-phenyl)fluorene, or on condensates, obtained under acid conditions, of phenols with formaldehyde such as phenol novolaks.
