METHODS FOR PREPARING ADVANCED EPOXY OR PHENOXY RESINS WITH LOW ALIPHATIC HALIDE CONTENT |
摘要 |
<p>Advanced epoxy resins having a low total aliphatic halide content are prepared by reacting an epoxy resin having an average of more than one 1,2-epoxide group per molecule with a material having an average of more than one phenolic hydroxyl group per molecule in the presence of a solvent having at least one aliphatic hydroxide group per molecule and a catalytic quantity of an alkali metal hydroxide. These low aliphatic halide-containing advanced epoxy resins are useful in formulations for preparing laminates, moldings, pottings and coatings for the electronics industry.</p> |
