    Abstract: Compact and preferably cellular polyurethane elastomers are produced by reactinga) polyhydroxyl compounds having molecular weights of from 800 to 6000 and, if desired,b) chain extenders and/or crosslinkers having molecular weights of up to 800 [lacuna]c) naphthylene 1,5-diisocyanate and at least one additional aromatic diisocyanate selected from the group consisting of tolylene diisocyanate, diphenylmethane diisocyanate, 3,3'-dimethylbiphenyl diisocyanate, 1,2-diphenylethane diisocyanate and phenylene diisocyanate, and/or aliphatic diisocyanate having from 4 to 12 carbon atoms and/or cycloaliphatic diisocyanate having from 6 to 18 carbon atoms, where the formative components (a), (c) and, if used, (b) are preferably reacted by the prepolymer method,in the presence or absence ofd) catalysts,e) blowing agents andf) additives. Isocyanate prepolymers suitable for this purpose are also described.

    Abstract: The invention concerns a method of preparing compact and preferably cellular polyurethane elastomers by reacting a) high molecular polyhydroxyl compounds and optionally b) low molecular chain-extending and/or crosslinking agents with c) 1,5-naphthylene diisocyanate and at least one additional aromatic diisocyanate, selected from the group comprising toluylene diisocyanate, diphenylmethane diisocyanate, 3,3'-dimethyl diphenyl diisocyante, 1,2-diphenylethane diisocyanate and phenylene diisocyanate, and/or aliphatic diisocyanate with between 4 and 12 carbon atoms and/or cycloaliphatic diisocyanate with between 6 and 18 carbon atoms, the structural components (a), (c) and optionally (b) advantageously being reacted by the prepolymer method, in the presence or absence of d) catalysts, e) expanding agents and f) additives. The invention further concerns isocyanate prepolymers suitable for this method.
