Description
An FTIR method has been developed to determine the presence and to quantify the concentration of two antioxidants in Extended Thermoplastic Rubber (ETPR) Cable Filling Compounds. The antioxidants are AO (thlodiethylene bis (3,5-di-tert-butyl-4-hydroxyhydrocinnamate) and AO2 (tetrakis(methylene(3,5-di-tert-butyl-4-hydroxyhydrocinnamate))methane). This method will monitor the presence and quantify the individual concentrations of AO1 and AO2 individually or as a binary antioxidant system.
