    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: Cellular polyisocyanate polyadducts are prepared by reacting (a) isocyanates with (b) compounds reactive toward isocyanates and (d) water, by a process in which a polyester having 2 hydroxyl groups and based on the condensation of at least one dicarboxylic acid with at least one alkanediol and/or alkenediol of 3 to 6 carbon atoms, whose carbon skeleton has at least one alkyl and/or alkenyl side chain between the hydroxyl groups, is used as (b).

    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.
