    Abstract: The present invention relates to a method for producing a composition (I) containing at least a compact thermoplastic polyurethane (P1), comprising providing at least one compound thermoplastic polyurethane (P1) or a reaction mixture for producing a compact thermoplastic polyurethane (R-P1), addition of at least one compound (N) having a conjugated, nitrogen-containing aromatic structure as a nucleating agent to the at least one thermoplastic polyurethane (P1) or the reaction mixture for producing a compact thermoplastic polyurethane (R-P1), wherein the compound (N) is a solid, and mixing of the nucleating agent and the thermoplastic polyurethane (P1)/of the reaction mixture (R-P1) to obtain a composition (I). The nucleating agent is employed in an amount in the range from 0.01 wt% to 2.0 wt% based on the thermoplastic polyurethane (P1)/the reaction mixture (R-P1). The present invention further relates to a composition containing at least a compact thermoplastic polyurethane and at least one compound (N) having a conjugated, nitrogen-containing aromatic structure as a nucleating agent, wherein the compound (N) is a solid, and to the use of the recited compounds as nucleating agents for a compact thermoplastic polyurethane.
