Research Progress of Pro-environment Thermal Stabilizers of PVC
The structural characteristics,thermal aging and thermal stability mechanism of poly(vinyl chloride) (PVC) were described. The research about traditional rare-earth,organic-tin,metal soap and compound hydrotalcite thermal stabilizer were intro-duced. Meanwhile,the some new green PVC thermal stabilizer,specially urea derivatives and metal alkoxides thermal stabilizers, were summarized,this new green PVC thermal stabilizer become an important direction for future.
