Inhibition of polyketone oxidation

Authors


Abstract

Oxidation of polyketones [poly(ethylene ketone) ([BOND]CH2[BOND]CH2[BOND]CO-)n and poly(propylene ketone) ([BOND]CH2[BOND]CH(CH3)[BOND]CO-)n] in the presence of antioxidant [2,2′-methylene-bis(4-methyl-6-tert-butylphenol)] was studied in the temperature range 120–190°C. The effectiveness of the antioxidant in polyketones is much lower than that in polyolefins. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 1182–1185, 2003
