ABS plastic

The effect of polystyrene modifier and diesterphthalic plasticizer nature on wettability of PVC by plasticizer and degree of its migration from the volume of the material is established. Встановлено вплив природи полістрольного модифікатора і диестерфталатного пластифікатора на змочуваність полівінілхлориду пластифікатором та ступінь його мігрування з об’єму матеріалу.

Poly(vinyl chloride) (PVC) has been modified by dissolution of polystyrene modifier in diesterphthalate plasticizer, followed by dispersive mixing with PVC. The effects of the kind of modifier and plasticizer used on the wetting of PVC by the plasticizer have been evaluated. The degree of plasticizer migration out of the material and the effects of the migration on mechanical and thermophysical properties of modified materials have been determined.
