| titleOfInvention | Bis(aminophenoxy)-alpha-substituted stilbenes, curable mixtures with epoxy resins and cured products |
| abstract | The present invention concerns bis(aminophenoxy)-alpha-substituted stilbenes represented by Formula (I) wherein each R is independently hydrogen or a hydrocarbyl or hydrocarbyloxy group having from one to about 10, preferably one to about 4, carbon atoms, a halogen atom, preferably chlorine, bromine or fluorine, a nitro group, a nitrile group or a -CO-R2 group; each R1 is independently hydrogen or a hydrocarbyl group having from one to about 10, preferably one to about 6, carbon atoms; X is a (a) or (b) group, each R2 is independently hydrogen or a hydrocarbyl group having from one to about 10, preferably one to about 2, carbon atoms; R3 is a hydrocarbyl group having from one to about 10, preferably one to about 2, carbon atoms and may be chlorine or a nitrile group, when n has a value of zero; and n has a value of zero or one. Bis(aminophenoxy)-alpha-substituted stilbenes are prepared by reacting a dihydroxy-alpha-substituted stilbene with a halonitrobenzene in the presence of a basic acting substance such as potassium carbonate and hydrogenating the resulting bis(nitrophenoxy)-alpha-substituted stilbene to convert the nitro groups to amino groups. These compounds are useful as curing agents for epoxy resins. |
