Abstract
An approach to estimating the efficiency of reduction in plasticizer leaching from a poly(vinyl chloride) (PVC)-based polymer is proposed. Experimentally, the leaching rate was reduced by adding a nanofiller based on heptakis-(2,3,6-tri-O-benzoyl)-β-cyclodextrin (Bz-β-CD) to the PVC. A decrease in the rate of the initial desorption stage depends on the nanofiller content, which determines the amount of leached plasticizer, which, in turn, causes a reduction in the desorption rate. Models for the influence of nanofiller content on the rate of the initial desorption stage and on the fraction of desorbed plasticizer, which diminishes the process intensity, are formulated.
