| titleOfInvention | Phenol derivatives and process for their production |
| abstract | The improved phenol derivatives having a phenolic structure as part of the molecular backbone are produced by reacting condensed polycyclic aromatic hydrocarbons, either individually or in combination with unsaturated cyclic aliphatic hydrocarbons, with phenols in the presence of Friedel-Crafts catalysts and have softening points of no more than 150° C., number average molecular weights of 250-800 and phenolic hydroxyl equivalents of 140-850 g/eq. These phenol derivatives are useful either as starting materials for the manufacture of heat-resistant thermosetting resins or as modifiers thereof. They can be produced by reacting the indicated components in the presence of Friedel-Crafts catalysts, typically a mixture of hydrogen fluoride and boron trifluoride, at temperature of 0-350° C. |
