[PDF] Kinetic Study of Effect of Irganox E Antioxidants on ...

The effect of three Irganox E-type antioxidants (E 17, E 120, and E 201), based on a-tocopherol, on poly (vinyl chloride) thermal degradation rate at 180 °C has been studied. Fifteen film samples, which consisted of suspension poly (vinyl chloride), lubricant, and antioxidant, were prepared. Four samples contained a Ca/Zn stabilizer system with an epoxy co-stabilizer and Irganox E 201.

Thermal stabilization of polyamide 11 by phenolic antioxidants

Abstract. This paper addresses the effect of hindered phenols (mainly Irganox 1098 with a few comparisons with other phenolic antioxidants) on the stabilization of polyamide 11 aged at several temperatures (90–165 °C). The effect of several phenol concentrations (up to about 0.4%) on kinetic curves for imide build-up, yellowing, and molar ...

An effficiency-decreasing effect of fillers on antioxidant Irganox-1010 and 'Methylene-4426-S' was also observed in the thermal oxidation of PP composites. It is proposed that the efficiency- decreasing effect of filler on stabilizers is caused by the adsorption of stabilizer molecules on the surface of the filler.

Study of thermal properties of antioxidant lipoamide and ...

Abstract Lipoamide (LM), amide of α-lipoic acid, is a very powerful antioxidant. However, information on its physicochemical properties, in particular on its thermal behavior, is very limited. In the present work, a DSC study of LM showed that heating above the melting point led to formation of a mixture of polymeric and crystalline forms of LM. In order to increase thermal stability of the ...
