| Abstract: | Stearate radical intercalated hydrotalcite was prepared by ion-exchange method and was characterized by infrared spectrum.The heat stability of the combination of stearate radical intercalated hydrotalcite and Ca/Zn heat stabilizer was studied by HAAKE Rheometer and UltraScan XE.The effect of hydrotalcite structure on the stability of PVC was studied emphatically.The results showed that the compounding of stearate radical intercalated hydrotalcite and Ca/Zn soap could improve the primary coloring ability obviously during the thermal aging of PVC. |
