ABSTRACT:
A stabilizer composition is described and comprises a 3-arylacrylate, a polymeric compound with molecular weight at least 2000, bearing, on a polymeric framework, side groups having amine functions, where all of the substituents in the α-position to the amine nitrogen atom are other than hydrogen, and comprises a sterically hindered phenol. The stabilizer composition is particularly suitable for stabilizing thermoplastic polyurethane with respect to light, oxygen, and heat.
