Abstract: The invention relates to a method for the preparation of cellular polyurethane elastomers with densities of approximately 250 to 800 grams per liter by reacting 4,4'-diisocyanato-1,2-diphenylethane or a diisocyanato-1,2-diphenylethane isomer mixture with a 4,4'-diisocyanato-1,2-diphenylethane content of more than 95 percent by weight with higher molecular weight polyhydroxyl compounds and water, as well as optionally chain extenders in the presence of auxiliaries and/or additives according to the one-shot or preferably the prepolymer method in closed molds. Compared with products based on 4,4'-diisocyanatodiphenylmethane, the polyurethane elastomer molded parts have improved physical and thermal properties.

Abstract: Process for applying a layer of electrically conductive polymers to other materials in which a solution of a monomer capable of forming an electrically conductive polymer is mixed with an oxidant and, if appropriate, with a conductive salt and immediately thereafter the mixture is applied to the surface of the material so that the monomer polymerises.

Abstract: The invention relates to a process for the manufacture of noncellular polyurethane elastomers by reacting 4,4'-diisocyanato-1,2-diphenylethane or diisocyanato-1,2-diphenylethane isomer mixtures with a 4,4'-diisocyanato-1,2-diphenylethane content in excess of 95 percent by weight, higher molecular weight polyhydroxyl compounds and low molecular weight chain extenders optionally in the presence of auxiliaries and additives. The polyurethane elastomers produced in accordance with this invention excel by a greater hardness and improved mechanical properties compared with polyurethane elastomers based on 4,4'-diphenylmethane diisocyanate with otherwise comparable composition.
