Additive Diffusion from LDPE Slabs into Contacting Solvents as a Function of Solvent Absorption

摘要

This article describes the simultaneous diffusion of a migrant and a solvent in low density polyethylene (LDPE).The migrant (Irganox 1076) moves out of the slab,while the solvent (isooctane,n-heptane or cyclohexane) moves inwards.Solvent absorption was measured separately by following the increase of the mass of the slab with time.
