Lanthanum stearate stabilizer was prepared by saponifying method and also characterized its structures by FTIR techniques and thermal properties by DSC techniques. Compared with traditional stabilizers, the lanthanum stearate stabilizer had better properties such as the stability and weather resistance,and could be used to prepare the PVC. The experiment results showed that the PVC properties were improved in heat-stability, processing behavior and mechanical properties by filled with lanthanum stearate stabilizes.
