Abstract
ADL Migration Estimation Model (AMEM) is a user friendly software package programmed for an IBM personal computer that provides the user with the ability to estimate the weight fraction of a chemical migrating from a polymeric material. The chemical may be an additive (e.g., a plasticizer) or unreacted monomer (e.g., styrene). The program estimates the migration of chemicals based on mathematical equations derived using diffusion and mass transfer theories. The user is prompted for chemical specific data such as molecular weight and vapor pressure of the migrant. The user may enter the diffusion coefficient for the polymer of interest or may use one of the default values provided by the software for six generic types of polymers with a wide range of diffusion coefficients. Background information, model development, mathematical calculations, example scenarios, and a user's guide are provided in the documentation.
