<p>1. Process for the preparation of polymer-bound carrier masses containing fillers, characterised in that A) fillers based on prefinished, lumpy or pulverulent voams and/or fossil ligno cellulose powders and/or carbon powders and optionally other inorganic or organic fillers and/or optionally living and/or dead biological cell material in a quantity of from 5 to 97% by weight, based on A) and B), are mixed with B) nonionic-hydrophilic, anionic or cationic, aqueous, coagulable and film forming polymer dispersions having a solids content of from 3 to 60% by weight, optionally with the addition of C) water so that the total water content, based on all components, amounts to 20 to 90% by weight, and optionally with the addition of D) other auxiliary agents and additives and the polymer dispersion is then brought to coagulation.</p> |
