Influence of Polyols as a Co-Stabilizer on Stabilization Efficiency of Calcium/Zinc Stabilizers to PVC/ACS Blend

Abstract:

In order to prepare good thermal stabilizer for PVC/ACS blends, the Congo red methods was adopted to determine the thermal stabilizing time of blends and study the synergy effect between polyols and Ca/Zn stabilizer for PVC/ACS blends. The rheological behaviors and dynamic mechanical properties of PVC/ACS blends were investigated by rotational rheometer and dynamic mechanical analyzer (DMA). The results showed that the different polyols have different influences on the thermal stability, melt viscosity, dynamic mechanical properties of PVC/ACS blends. The pentaerythritol has a good synergy effect with Ca/Zn stability and the PVC/ACS blend has a lower melt viscosity.
