resistant oxidation agent composite/compounding use 常出现两 types 效应: 协同效应 and resistant 协同效应. types or types above resistant oxidation agent use, if ratio mono use types more good, is 协同效应, if it ratio mono types more 糟糕, is resistant 协同效应. function separation 子间协同 function and separation inner function, its in separation 子间协同 function also can separation is below/following types:

(1)ho-mo-synergi sm指 tool has same resistant oxidation mechanism resistant oxidation agent between function.

(2)Heter-synergi sm is tool has different resistant oxidation mechanism resistant oxidation agent between function, separation inner function also 称自动协同 function, this 意味 一 types resistant oxidation agent has more can 团, it between tool has function.

当两 types 空间位 retardant different （羟基邻位取代基 different ） 酚 type resistant oxidation agent meanwhile use, or resistant oxidation active property different amine type and type resistant oxidation agent meanwhile use 时, tool has function. AH is high retardant retardant or low active property resistant oxidation agent, BH is low retardant retardant or high active property resistant oxidation agent. it and oxidation material 自由基 reaction 时, BH more easy reaction. high active property resistant oxidation agent oxygen gas agent can has 效 捕获 oxidation property 自由基 or oxidation property 自由基. 此时, low active property resistant oxidation agent can to hydrogen 原子, make high active property resistant oxidation agent recycled, maintain long resistant oxidation efficiency. therefore, this types resistant oxidation agent use rear can generate function.

辅助 antioxidant and antioxidant combined is non-uniform 协同效应 一 例子. table/sheet 明, type resistant oxidation agent and acid ester between in function. type antioxidant as is main/primary resistant oxidation agent, tool has active hydrogen 原子, ratio polymer carbon upper hydrogen 原子（包括 carbon upper belt/tape di hydrogen ） more active 泼, can and large separation 子链自由基R or R0O separation combined. formed oxidation hydrogen and stability oxygen 基自由基.

due to oxygen 基 邻位取代数 increase or its separation increase more, increase retardant function, make its can by versus more large 体积基团保护, improve/increase oxygen stability property. in addition, due to oxygen 基自由基 and ring in large system in, versus for stability, active property low, can 引发链式 reaction, can and active property 自由基结 combined, again 次终止一 自由基, formed more stability combined material, from 而终止链式 reaction. oxygen 基自由基 this type of stability property anti resistant oxidation agent by oxidation fast consumption, decrease/reduce 链转移 reaction, from improve/increase it resistant oxidation property can.

is anti 止链式 reaction and more good 切断链生 long reaction, need use types can separation understanding large separation hydrogen antioxidant can formed stability combined material, anti 止链式 reaction development. this type of separation understanding oxidation hydrogen resistant oxidation agent is resistant oxidation agent. therefore, utilizing resistant oxidation agent, resistant oxidation agent and stabilizer between function, can made various has composite/compounding stabilizer. currently sales many composite/compounding resistant oxidation agent is retardant and acid ester combined material, BASF company Irganox B series is antioxidant 1010, Irganox 1076, Irganox 1330 and Irganox 168按不 year-on-year mixed combined formed.
