Abstract

Light-stable, sinterable, thermoplastic polyurethanes with improved blooming behavior and good thermal stability as well as good technical processability are produced from an aliphatic diisocyanate using one or more chain extenders corresponding to a specified formula. These polyurethanes are particularly useful in the production of molded articles, particularly molded articles for automotive interiors.
