ukusetyenziswa
I-AIBN sisixhobo esibalaseleyo sokuqalisa ii-free radicals. Xa ifudunyezwa ukuya kuthi ga kwi-70 ° C, iyabola kwaye ikhuphe igesi ye-nitrogen, ivelise ii-free radicals (CH3) 2CCN, ii-Free radicals zizinzile ngakumbi ngenxa yempembelelo yamaqela e-cyanide. Ingasabela kwenye i-substrate yendalo, izitshabalalise, kwaye iphinde ikhule ibe yi-free radical entsha, ngaloo ndlela ibangele ukusabela kwe-chain yee-free radicals (jonga impendulo ye-free radical), Xa ifudumeza i-AIBN ukuya kwi-100-107 ° C, iyanyibilika kwaye ibole ngokukhawuleza,
Isetyenziswa njengesiqalisi sepolymerization kwiimonomers ezifana ne-polyvinyl chloride, i-polyvinyl alcohol, i-polystyrene, kunye ne-polyacrylonitrile. Isetyenziswa njengesiphakathi kwi-organic synthesis. Isetyenziswa njengesiqalisi see-polymers ezineemolekyuli ezininzi.
Isetyenziswa njengomqalisi we-polymerization okanye i-copolymerization ye-vinyl acetate kunye ne-acrylic esters.
Isetyenziswa njengearhente yokufutha.
Ukusetyenziswa: Isixhobo sokufaka izicubu kwi-methyl methacrylate. Umqalisi we-polymer. Irabha, iplastiki, iarhente yokufutha. Isixhobo sokuvuselela iplastiki sePolychloroethylene
