| Abstract: | We researched the effects of adding hindered amine light stablizier(HALS),hindered amine free radical,antioxidant to polypropylene on yellowness index of polypropylene under the irradiation condition.The results showed that the yellowness index of polypropylene added pentanethyl HALS was much less than the polypropylene added tetramethyl HALS;however,yellowness index of polyprophlene added pentamethyl hindered amine free radical was also less than those added tetramethyl hindered amine free radical |

| Keywords: | polypropylene hindered amine light stablizer(HALS) hindered amine free raical yellowness indes antioxidant |
