Diffusion and solubility of hydroxy compounds in polyolefines

The diffusion and relative solubility coefficients of some alcohols, phenols, and antioxidants have been measured by a permeation method for LDPE at room temperature. The diffusion coefficients of the hydroxy compounds are compared with those of the alkanes. The diffusion coefficients of the alkanes mark out upper limiting values which are not exceeded by the hydroxy compounds of comparable molecular weight.
