Synergistic effect of phosphite with fullerene C60 and

TGA and OIT tests showed that the stability effects of fullerene and fullerenol were slightly lower than antioxidant 1010. In the first time, antioxidant 168 was reported to show great synergistic effects with fullerene and fullerenol as antioxidants, which sussested a simple way to enhance the antioxidative abilities of fullerene and fullerenol.

Performance and antioxidant activity of phenol/phosphite

The influence of zinc stearate (ZnSt) on the thermal and photochemical stabilities of phenolic antioxidant/phosphite combinations has been determined in HDPE by using FTIR analysis. The results show that while under thermal aging the effects are generally antagonistic, under photooxidation the effects are synergistic. The interactions appear to be dominated by the role of complex formation

Secondary Antioxidant. Secondary AOs become cost effective when they can lower the required amount of more expensive primary AOs. And some high-performance, phosphite-based secondary AOs have even been shown to maintain a resin’s color and melt flow properties in PP when used as the sole processing stabilizer—without any primary phenolic AO in the formulation [1-1, 3-3, 3-4, 3-12][1-1][3-3
