Txhawm rau txhim kho lub peev xwm antioxidant ntawm cov khoom ua npuas ncauj, peb ntxiv cov tshuaj antioxidants rau cov txheej txheem polyether ntau lawm thiab ua npuas dej (qhov kub ntawm cov khoom ua npuas tuaj yeem nce mus rau ntau tshaj 180 degree, thiab cov nyiaj ntxiv yog cuam tshuam nrog cov dej ntxiv).
Cov xim tus nqi yog qhov pom tseeb tshaj plaws ntawm qhov pom tseeb ntawm polyether, thiab qhov zoo ntawm cov nqi xim tuaj yeem cuam tshuam ncaj qha rau qhov zoo ntawm polyether.Cov pa roj carbon atoms ntawm polyetherether daim ntawv cog lus yog yooj yim oxidized, tshwj xeeb tshaj yog nyob rau hauv alkaline xov xwm thiab kub siab, uas yuav ua rau ib tug nce nyob rau hauv cov kev xav ntawm sab thiab tsim unsaturated bonds. Yog tias tus nqi xim tsaus nti, lwm cov cim qhia (xws li AV, unsaturation, thiab lwm yam) kuj yuav hloov raws li, thiab xim ntawm cov khoom ua npuas ncauj yuav hloov raws li.
