Ubusanzwe polymer iba imeze nabi mugihe cyo gutunganya ibicuruzwa, kandi sisitemu irimo umubare munini wa karubone ya karubone aho kuba alkoxy radicals na hydroxyl radicals.Kubwibyo, uburyo bwiza bwo gutunganya stabilisateur bugomba kuba bushobora gufata neza radicals yubusa.Antioxydants ya hydroxylamine yavuzwe haruguru ni ubwoko bwa carbone radical umutego.
Ibikoresho nyamukuru byangiza imyuka ya karubone ku isoko ni hydroxylamine, bisphenol mono-acrylate, ortho acrylyl yasimbuye fenol na benzofuranone ibyiciro byinshi.
Antioxydants ya Bisphenol monoacrylate:
Muri molekile ya bisphenol monoacrylate, radical ya karubone ifatwa nitsinda rya acrylyl, kandi radical enol radicals ishobora guhinduka muburyo bukomeye bwa ogisijeni ya ogisijeni ihamye hamwe nitsinda rya hydroxyl rikora muri molekile imwe.Ingaruka izwi nkuburyo bwo guhuza ibikorwa.Ibi biha bisphenol monoacrylate imbaraga zikomeye zubusa zo gufata imitego.Guhagarara kwayo birakomeye no mubushyuhe bwinshi.Amasosiyete yo mu Buyapani no mu Burayi yashyize ahagaragara ibicuruzwa nkibi.Kugeza ubu, Sumilizer GM na Sumitomo Chemical, IRGANOX 3052 na BASF, na AO3352 / AO3353 ikoreshwa cyane ku isoko.
