Abstract: Compact and preferably cellular polyurethane elastomers based on polyisocyanate mixtures containing 3,3'-dimethylbiphenyl 4,4'-diisocyanate are produced by reactinga) relatively high molecular weight polyhydroxyl compounds and, if desired,b) low molecular weight hydroxyl-containing chain extenders and/or crosslinkers withc) 3,3'-dimethylbiphenyl 4,4'-diisocyanate and at least one additional aromatic diisocyanate selected from the group consisting of tolylene diisocyanate, diphenylmethane diisocyanate, 1,2-diphenylethane diisocyanate and phenylene diisocyanate, and/or at least one aliphatic diisocyanate having from 4 to 12 carbon atoms and/or at least one cycloaliphatic diisocyanate having from 6 to 18 carbon atoms, where the formative components (a), (c) and, if used, (b) are advantageously reacted by the prepolymer method,in the presence or absence ofd) catalysts,e) blowing agents andf) additives.Isocyanate prepolymers suitable for this purpose are preferably ones based on diphenylmethane 4,4'-diisocyanate and 3,3'-dimethylbiphenyl 4,4'-diisocyanate.

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, 1,2diphenylethane 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.
