PROCESS FOR PREPARING RESIN IMPREGNATED SUBSTRATES FOR USE IN PREPARING ELECTRICAL LAMINATES |
| 摘要 |
<p>The preparation of substrates impregnated with epoxy resins and curing agents therefor is improved by employing as the epoxy resin one which has been prepared by reacting a low equivalent weight epoxy resin having an aliphatic halide content of at least 500 ppm such as a diglycidyl ether of bisphenol A with a dihydric phenolic compound such as tetrabromo bisphenol A in the presence of an alkali metal hydroxide such as potassium hydroxide. 28,237-F</p> |
