Abstract
Poly(vinyl chloride) was reacted with sodium N‐methyl dithiocarbamate to produce a modified PVC containing N‐methyl dithiocarbamate of varying degrees of substitution. The resulting adducts were markedly more stable when subjected to γ‐radiation than the unmodified PVC. The transport parameters (permeability, solubility, and diffusivity) of fixed gases were determined in modified and unmodified films. Although the radiation stability was dramatically improved by this novel substitution, the barrier properties of the PVC were only slightly changed by the controlled substitution of N‐methyl dithiocarbamate.Keywords
