| titleOfInvention | Processes for preparing hydroxyaromatic oligomers containing triazine groups and for preparing epoxy resins from the oligomers |
| abstract | This invention pertains to a process for preparing hydroxyaromatic oligomers containing triazine groups. The process is characterized by (1) reacting (A) a material having an average of more than one aromatic hydroxyl group per molecule such as bisphenol A with (B) a cyanogen halide such as cyanogen bromide in the presence of (C) a base and recovering a mixture of cyanate-containing products and unreacted (A) materials; (II) trimerizing the product recovered in (1) in the presence of a trimerization catalyst such as cobalt naphthenate. This invention also pertains to a process for epoxidizing the product from step II by reaction with an epihalohydrin such as epichlorohydrin, dehydrohalogenation of the resultant product with a basic-acting material such as sodium hydroxide and recovering the resultant epoxy resin containing triazine groups. |
