Abstract. It also appears to improve the activity of the hindered amine stabilizer that is also a component of the system, as both a thermal and light stabilizer. Phosphite/phosphonites are generally regarded as the most effective stabilizers during processing, protecting both the polymer and the primary antioxidant.
