Polyamide-imide powders, preparation process and use |
| abstract |
The polyamide-imide powders of the invention are infusible and consist of grains of spheroidal shape whose diameter is between 2 and 40 microns.n n n They are obtained by anionic polymerization of lactams using a catalyst and a polyisocyanate added in sufficient quantity so that it firstly activates the polymerization and, then, reacts with the polyamide chains formed.n n n Such powders are advantageously used as additives for lubricants. |
