Phenanthrene/HCHO derived polyamide-imide |
| abstract |
This invention relates to thermally stable resins and provides such a resin made from cheaply available coal-derived materials, whereas presently available resins are made from increasingly expensive oil-derived materials. n The resin comprises the condensation product of a reaction between an aromatic diamine and a phenanthrene-formaldehyde reaction product, which product has been oxidized to produce keto groups bridging the phenanthrene moieties and carboxy groups. The condensation product is a poly-(amide-imide). n The invention also includes a method of making the resin and varnishes containing the resin. n The resin will find use for instance as a high temperature insulator or in glass or asbestos laminates in compressor blades. |
