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