ABSTRACT: This aim of this work is to study the
partial replacement of the plasticizer ordinarily used di-octyl phtalate (DOP) by the
permanent plasticizers ethylene-vinyl-acetate (EVA) and acrylonytrile-bu- tadiene-styrene
(ABS) in order to reduce migration of additives initially contents in polyvinyl
chloride (PVC) stabilized with expoxidized sunflower oil (ESO). Migration tests
with agitation to 40°C in sunflower oil and ethanol at 15% were made. Migration
phenomenon was studied on the basis of the PVC samples mass variations, Fourier
transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM)
analysis. The results showed the effectiveness of the approach consisting in
the partial substitution of DOP by plasticizers of polymeric nature. The following
order concerning the migration of additives was found: DOP (40) > DOP:EVA >
(30/10) DOP:ABS (30/10). Furthermore, all the measured values of overall
migrations were lower than the maximum allowable overall migration: 10 mg-dm-2.
