Abstract

Described is a stabilizer composition comprising a 3-arylacrylic ester, a polymeric compound having a molecular weight of at least 2000 which carries, on a polymeric framework, side groups having secondary amine functions, all substituents positioned to the amine nitrogen being other than hydrogen, a chroman derivative, and an organic phosphite and/or phosphonite. The stabilizer composition is particularly suitable for stabilizing thermoplastic polyurethane against light, oxygen and heat.
