Abstract
The rate of loss of the antioxidant 2‐tertiary‐butyl‐4‐methoxy phenol (BHA) from high‐density polyethylene (HDPE) was determined using high pressure liquid chromatography (HPLC). The rate of loss was found to follow a first‐order expression. Almost all of the antioxidant was lost (>95 percent) within 1 day at 50°C, within 3 days at 40°C, and within 7 days at 30°C. The controlling parameter for mass transfer of the antioxidant was found to be volatilization rather than diffusion.Keywords
