2-hydroxy-4-methoxybenzophenone-5-sulfonic acid (BP) anion-intercalated Mg-Al-carbonated layered double hydroxide (LDH) (LDH-BP) was prepared by an ion-exchange method. The structure of LDH-BP was characterized by XRD, FTIR and TG-DTA. The accelerated weathering and thermal stability of PVC/LDH-BP composites were investigated by color change, oxidation products, surface morphology, and thermal stability time. In addition to the sacrificing role of BP anion structure by absorbing the incident light and transmitting the rest of the light in a non-harmful form, the ability of LDH-BP to scatter the incident light and to absorb the released HCl improves the resistance to both accelerated weathering and thermal degradation.
