kev siv

AIBN yog ib qho tshuaj pib dawb zoo heev. Thaum cua sov txog li 70 ° C, nws lwj thiab tso cov pa nitrogen, tsim cov dawb radicals (CH3) 2CCN. Cov dawb radicals ruaj khov dua vim muaj kev cuam tshuam ntawm cov pab pawg cyanide. Nws tuaj yeem cuam tshuam nrog lwm cov organic substrate, rhuav tshem nws tus kheej, thiab rov tsim dua tshiab rau hauv cov dawb radical tshiab, yog li ua rau muaj kev sib txuas ntawm cov dawb radicals (saib cov tshuaj tiv thaiv dawb radical), Thaum cua sov AIBN txog 100-107 ° C, nws yaj thiab dhau los ua kev lwj sai,

Siv ua tus pib polymerization rau cov monomers xws li polyvinyl chloride, polyvinyl cawv, polystyrene, thiab polyacrylonitrile. Siv ua ib qho nruab nrab hauv kev tsim cov organic. Siv ua tus pib rau cov polymers molecular siab.

Siv ua tus pib rau polymerization lossis copolymerization ntawm vinyl acetate thiab acrylic esters.

Siv ua tus neeg sawv cev ua npuas ncauj.

Daim Ntawv Thov: Ib qho catalyst rau kev muab cov ntaub so ntswg rau hauv methyl methacrylate. Tus pib ntawm polymer. Roj hmab, yas, tus neeg sawv cev ua npuas ncauj. Polychloroethylene yas activator
