FILLER-CONTAINING POLYURETHANE(UREA) COMPOSITIONS AND PROCESS FOR THE PRODUCTION THEREOF ABSTRACT OF THE DISCLOSURE The invention relates to a process for the production of polyurethane(urea) compositions which contain lignite and/or peat bound in an abrasion proof manner, which are preferably modified cationically and which have a very high water absorbability. The compo- sitions are produced by reacting isocyanate-terminated prepolymers, which are preferably cationically modified, and which preferably have a functionality of more than 2.1, with more than the stoichiometric quantity of water in the presence of lignite and/or peat and optionally in the presence of organic and/or inorganic fillers and biomasses (living cells; living bacteria or enzymes). The corresponding polyurethane(urea) compositions contain up to 95% by weight of lignite and/or peat in the filler-containing polyurethane(urea) composition and are already swollen from production. The water absorb- ability (WAF) value thereof when suspended in water is from 33 to 97% by weight of water. The compositions can be used, in a form option- ally containing biomasses incorporated therein, as carriers in microbial synthesis processes for the production of complicated organic compounds, or as carriers for the growth of plants.
