Polymer stabilization has been an active area of research and development for several decades. In this review, advances in phosphite chemistry are discussed with regard to hydrolysis resistance and color retention. The use of lactones as carbon centered radical traps is reviewed with examples showing the increase in performance over traditional base stabilization systems. Discoloration issues arising from hindered phenolic antioxidants are outlined, and, N,N‐dialkylhydroxylamine chemistry is reviewed as a means of avoiding phenolic discoloration while providing polymer protection. Color fading in demanding fiber applications is explored as well as a new stabilizer designed for color retention. The elimination of acid‐base interaction with NOR hindered amines is considered especially as it pertains to acidic polymer applications such as flame retardant end uses and agricultural films. Hindered amine stabilization chemistry and NOR performance data are discussed.
