<p>A polyimide resin is made by converting a phanthrene to its 9, 10 diol derivative, reacting the derivative with formaldehyde to give a methylene bridged reaction product, oxidizing the reaction product to produce a polycarboxylated product, and reacting the polycarboxylated product with an aromatic diamine to form the polyimide resin. The invention also includes the resin, the reaction product and the polycarboxylated product. The resin will be useful as a lamp capping cement, a high temperature insulator, in copper clad printed circuit boards, in glass or asbestos laminates for use as compressor blades.</p> |
