Abstract
A semi-empirical model has been developed for additive diffusion in po lymers. The model estimates apparent diffusion coefficients of an addi tive migrating through polyolefin polymers into a fatty food simulant for a range of temperatures between the glass transition and melting t emperatures of the polymer. This diffusion model has been applied to s everal additive/polyolefin systems to determine its validity and limit ations.
