Due to its structural drawback

halogenated organic compound

such as PVC and chloroparaffin is easily degraded under heat to form hydrogen chloride

leading to decomposition of such halogenated compound and damage to process equipment.Addition of thermal stabilizer in the halogenated compound can prevent those disadvantages.The usage of traditional thermal stabilizer come under limitation due to toxic heavy metal.Therefore novel thermal stabilizer

in particular organic thermal stabilizer

is the objective of research.Based on traditional thermal stabilization mechanism

polyols which have better stability or synergistic stabilization effect were chosen as lead compounds.These polyols were modified by esterification and etherification to introduce epoxide groups for enhancing stability and ester groups or ether groups for increasing dissolving and dispersing quality with PVC.The effect of such thermal stabilizers was investigated.Polyol derivatives with higher stability and excellent performance were obtained

such as triethylene glycol diglycidyl ether

glycerol epoxy resin and bisphenol A type epoxy resin.It will provide a reference for further research on organic stabilizer.
