| titleOfInvention |
Phenanthrene-derived thermally stable polyamide-imide resins and process for their preparation |
| 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 increasinly 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 oxidised to produce keto groups bridging the phenanthrene moeties 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. |
