Description

Analysis Note Phenolic Antioxidants are added to polyers for controlling their degradation process. Irgafos 168, Irganox 1010, Ethanox 330, Irganox 1076, BHT, and Irgafos 168 are often used as antioxidants to prevent the degradation of polypropylene polymer forµlations. This HPLC method is for the quantitation of an additive or mix of additives in a polymeric material.
