چکیده:

The stabilization effect of calcium and zinc stearates (CaSt2/ZnSt2) combined with Sb3+Y zeolite on
poly(vinyl chloride) is investigated. The results show that the addition of calcium/zinc stearates combined
with Sb3+Y can improve thermal and colour stability of poly(vinyl chloride) in both static and dynamic tests.
Mechanisms for improving stability of PVC are also discussed. The increase of stabilizing effectiveness of
calcium/zinc stearates is ascribed to the synergistic effect between CaSt2/ZnSt2 and Sb3+Y zeolite.
