Migration of plasticizers from plasticized polyvinyl chloride films

The migration of plasticizers [EDOS, di(2-ethyl hexyl) o-phthalate, di-n-butyl o-phthalate] from unfilled and chalk-filled polyvinyl chloride films plasticized with individual and binary plasticizers was studied by gravimetric analysis and IR spectroscopy. The intermolecular interaction of components in model systems was studied by IR spectroscopy and isothermal calorimetry.
