摘要
The invention is directed to the formation of filler containing anionically modified polyurethane (urea) compositions by reacting suitable polyurethane (urea) forming ingredients in the presence of from 5 to 97% by weight of fillers selected from the group consisting of (i) finely divided or lumpy foam particles, (ii) fossile lignocelluloses, (iii) carbon powder, and (iv) mixtures thereof, said filler-containing polyurethane (urea) having a water absorbability of from 33 to 97% by weight, and having an anionic group content of from 10 to 3000 milliequivalents of anionic groups and/or groups capable of anionic group formation per 1000 grams of said polyurethane (urea) components.
