Abstract: Polyurethane elastomers having improved behavior towards antistatic charge are produced by including an antistatic component in the polyurethane-forming reaction mixture. The antistatic component includes at least one quaternary alklyammonium monoalkylsulfate corresponding to a specified formula and at least one compound selected from (i) linear, OH-group-free dicarboxylic acid esters corresponding to a specified formula and/or (ii) a specified group of lactones. These polyurethane elastomers are particularly useful for the production of rollers, spring elements, mats and cushions, safety components in motor vehicles, shoe soles and shoe components.
