Procedure

The epoxy compounds can also derive from mononuclear phenols, for example from phenol, resorcinol, or hydroquinone; or they can be based on polynuclear phenols, for example on bis(4-hydroxyphenyl)methane, 2,2-bis(4-hydroxyphenyl)propane, 2,2-bis(3,5-dibromo-4-hydroxyphenyl)propane, 4,4′-dihydroxydiphenyl sulfone, or condensates obtained under acidic conditions from phenols with formaldehyde, e.g. phenol novolacs.
