Abstract The sorption of vapors of 2,6-di-tert-butyl-4-methylphenol (DTP) by HDPE containing different concentrations of heptadecane has been studied using the ultraviolet spectrometry method. The isotherms of DTPh sorption at 100–200°C are presented by the Langmuir equation. The concentration of sorption of DTPh has no dependence on temperature, but depends on the concentration of heptadecane in a polymer. The heats of dissolution of DTPh in polyethylene have been determined. Key Words: Sorptionpolyethylene
