Abstract: Moulded bodies are described which comprise a humus-containing plant substrate consolidated with polyurethane/polyurea, which are obtainable by slurrying a humus-containing plant substrate in water, admixing a liquid NCO prepolymer having a maximum NCO content of 15% by weight which has been produced by the reaction of toluene diisocyanate with a polyether polyol component containing at least one aminopolyether polyol in an amount of 0.5 to 100 mole % with respect to the polyol component, and introducing the mixture thus obtained into a mould and allowing it to solidify. A process for producing these moulded bodies is also described, as is their use as growth media for seedlings in the propagation and raising of plants.

Abstract: The instant invention is directed to a process for the production of a cellular polyurethane elastomer having a density of 0.45 to 0.8 g/cm.sup.3, comprising:(a) preparing a prepolymer having an isocyanate content of 10 to 25% by weight from aromatic polyisocyanates and a portion of one or more polyhydroxyl compounds having a molecular weight of from 400 to 6,000; and(b) reacting said prepolymer with the remainder of said polyhydroxyl compound and water;wherein the quantity of said water is 0.3 to 1% by weight and the equivalent ratio of isocyanate groups to isocyanate reactive compounds is in the range of 0.95:1 to 1.1:1, characterized in that from 0.1 to 0.8% by weight, based on the whole reaction mixture, of aromatic diprimary diamines having a molecular weight from 108 to 500 are also used in (a) or (b).
