Preparative HPLC followed by GPC-MS to investigate the potential leachable compounds produced by the degradation of pentaerythritol tetrakis (3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate)
Pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate) is a highly effective sterically hindered primary phenolic additive which protects polymers against thermo-oxidative degradation.
