摘要： For the continuous automated production of powders that are well suited for hot pressing, i.e. those consisting essentially of spherical or cubic particles, of high-temperature resistant polymers without damage to the polymer structure in the course of the production process, a concentrated solution of the polymer in an aprotic polar solvent is continuously expressed into a twisting cone of hot aqueous precipitant. In doing so, short irregular wormy formations form, which are united to a fleece-like web, washed with aqueous solvents and finally with water, dried and comminuted. The plant provided for carrying out the process requires comparatively little space, since it does not include treatment tanks for extraction and drying.
