    Abstract: This invention relates to polyurethane(urea) compositions which contain foam and which are preferably cationically modified, contain non-abrasively bonded fillers and have a very high water absorbability (WAF).Production is effected by reacting isocyanate-terminated prepolymers with a quantity of water far exceeding the stoichiometric quantity in the presence of foams in particle or film form. The reaction mixture may also contain lignite powder and/or peat, other inorganic and organic fillers and/or biomasses (living cells, living bacteria, enzymes).The polyurethane(urea) compositions contain up to 95% by weight of foam particles and may contain further fillers (preferably lignite and/or peat). The compositions are swollen and have a high water content during production. Their water absorbability (WAF) when suspended in water is 33 to 97% by weight of water. They can be used as carriers in microbic synthesis processes for the production of complicated organic compounds (when they have incorporated biomasses) as special carriers for the growth of plants, as filter agents or as adsorbents for non water-soluble liquids [for example, crude oil or petrol].
