A process for preparing epoxy resins |
| abstract |
According to the invention, an epoxy oligomerization catalyst can be employed to prepare an epoxy resin using a process comprising mixing a first epoxy resin having a first epoxy equivalent weight of from about 100 to about 600 with a diphenolic compound and a catalyst, thereby forming a second epoxy resin having a second equivalent epoxy weight of from about 200 to about 10,000; the catalyst being a guanidinium-based catalyst. The second equivalent weight is greater than the first equivalent weight. |
