Abstract: The paper summarized the thermal degradation mechanisms of poly(vinyl chloride) (PVC) and its thermal stabilization mechanisms with rare-earth thermal stabilizers. The main properties of rare-earth thermal stabilizers were introduced, and their development status was discussed. Their future research direction and development trend were pointed out.

Key words: poly(vinyl chloride), thermal stabilizer, rare-earth
