Diffusion of Additives and Plasticizers in Poly(Vinyl Chloride)-III Diffusion of Three Phthalate Plasticizers in Poly(Vinyl Chloride)loss of plasticizer from the surface of any artefact will depend, amongst other things, on the rate of diffusion to the surface. In order to assess plasticizer mobility, the self-diffusion coefficients of di-n-butylphthalate, di-n-hexylphthalate, and di-n-decylphthalate have been obtained in PVC over a range of concentrations and temperatures. |
