    Hindered Phenols Antioxidants for Plastics amfine

    Hindered phenols are primary antioxidants that function by scavenging peroxy radical intermediates in the oxidation process. They are effective over a wide range of temperatures and provide protection during melt processing, end use, and long-term storage. As processing stabilizers, hindered phenols serve to minimize changes in melt viscosity and reduce discoloration. During end use at

    In this case, phenols are combined with photoantioxidants (hindered amine stabilizers, HAS) and UV absorbers (light stabilizers). The concentration level of phenols added to plastics is generally between 250 and 3000 ppm, depending on the character and expected lifetime of the polymer substrate [1]. Similar concentration levels of phenolics are used for the restabilization of recycled plastics

    The antioxidant capabilities of phenols are strongly reduced by hydrogen-bond accepting solvents since the hydrogen-bonded molecules ArOH---S are virtually unreactive toward ROO* radicals. The magnitude of these kinetic solvent effects is determined by the solute acidity alpha(2)(H) of ArOH (range 0 to 1) and solvent basicity beta(2)(H) (range 0 to 1).
