摘要：

The paper presents an overview of the thermal stabilizing behavior of Li-Al-X LDHs (layered double hydroxides) system when used in poly (vinyl chloride) as a stabilizer. Layered lithium aluminium double hydroxides having anions CO32-, SO42-, NO3- and Cl- have been synthesized by the hydrothermal method. The effects of the synthesis conditions on the structural and textural properties as well as on the thermal stability were investigated using different methods. The study suggests that, in contrast to the Mg-Al-X, Ca-Al-X LDH system where LDH having CO32- in interlayer is proven best, Li-Al-X LDH, the Cl- in the interlayer proves to be a better anion to impart thermal stabilization to PVC.
