Abstract: The present invention relates to a method of using a composition (Z1) at least comprising an elastomer (E1) and an at least 90% carbon-based conductivity-conferring additive (A1) in the manufacture of an electrically heatable shaped article for the automotive sector, wherein said composition (Z1) has a Shore hardness A, determined as per DIN 53505, in the range from 30 to 95, an electric specific volume resistivity, determined as per ISO 3915, of below 1×102 ohm×cm and above 0.01 ohm×cm, and also a breaking extension, determined as per DIN 53504, of above 300%. The present invention further relates to a method of preparing an electrically heatable shaped article for the automotive sector comprising a composition (Z1) and also to electrically heatable shaped articles for the automotive sector comprising a composition (Z1).

Abstract: The invention provides a process for preparing thermoplastic polyurethanes by reacting a) polyisocyanates with b) compounds having at least two hydrogen atoms which are reactive toward isocyanate groups, wherein at least one monofunctional compound which is reactive toward isocyanates or/and at least one monofunctional isocyanate is added to the starting materials, the reaction mixture and/or the finished thermoplastic polyurethane.
