A process for advancing epoxy resins in molecular weight and a process for preparing resin impregnated substrates |
| abstract |
Process for advancing epoxy resins in molecular weight and a process for preparing resin impregnated substrates in which an epoxy resin is reacted with a dihydric phenol in the presence of a sufficient quantity of a phosphonium catalyst such that the product resulting from reacting a mixture of the catalyst, epoxy resin and dihydric phenol has a percent epoxide difference from the theoretical percent epoxide of from 0.5 to 4.0. |
