摘要:
The antioxidants, 3, 5-di-tertiary-butyl-4-hydroxy toluene (BHT) and α-tocopherol were incorporated into multilayer coextrusions consisting of a heat-seal layer, a core layer of high-density polyethylene (HDPE) impregnated with antioxidant (either BHT or α-tocopherol), and an outer HDPE layer. The rates of loss of the antioxidants from the respective films were determined as a function of time and temperature, using ultraviolet spectrophotometric and high-pressure liquid chromatographic procedures.
