| titleOfInvention | Method of producing an improved poly-(amide-imide) resin |
| abstract | This invention relates to an improved poly-(amide-imide) resin, a process for its preparation and its use as a temperature resistant resin. …<??>According to the present invention, there is provided an improved method of producing a poly-(amide-imide) resin comprising the steps of;… (1) reacting a phenanthrene with formaldehyde or a formaldehyde donor in the presence of an acid catalyst to give a phenanthreneformaldehyde reaction product having substantially only methylene bridges;… (2) removing from the reaction product unreacted phenanthrene;… (3) treating the reaction product with formaldehyde or a formaldehyde donor in the presence of an acid catalyst to give a high molecular weight product having substantially only methylene bridges;… (4) oxidising the high molecular weight product to break the 9, 10 bond in the phenanthrene moieties to produce a polycarboxylated reaction product;… (5) reacting the polycarboxylated reaction product with an aromatic diamine to produce a poly-(amide-imide) resin. …<??>The resin would find use as a lamp capping cement, as a high temperature insulator, in copper clad high temperature printed circuits, in electrical heater panels, in transformers and in glass or asbestos laminates for use as compressor blades. |
