Abstract

A stabilizer composition is described and comprises a 2-cyano-3,3-diarylacrylate, a sterically hindered monomeric amine, a sterically hindered phenol and, where appropriate, a chromane derivative and/or an organic phosphite and/or phosphonite. The stabilizer composition is particularly suitable for stabilizing thermoplastic polyurethane with respect to light, oxygen, and heat.
