摘要: This invention discloses blends of phosphites comprising bis-(2,4-dicumylphenyl) pentaerythritol diphosphite and hindered phenol antioxidants useful as stabilizers against thermooxidative degradation of polymers during melt processing. Polymer compositions comprising the blends show improved resistance to thermooxidative degradation during melt processing as measured by melt flow index and yellowness index.
