Hangata polymer e boemong ba anoxic tlas'a maemo a ts'ebetso ea extrusion, 'me tsamaiso e na le palo e kholo ea lik'hemik'hale tsa carbon ho e-na le li-alkoxy radicals le hydroxyl radicals.Ka hona, stabilizer e nepahetseng ea ts'ebetso e lokela ho khona ho hapa li-radicals tsa mahala tsa carbon ka nepo.Hydroxylamine antioxidant e boletsoeng ka holimo ke mofuta oa carbon radical trapping agent.
Lisebelisoa tse ka sehloohong tsa ho ts'oara li-radical tsa mahala tsa khabone 'marakeng ke hydroxylamine, bisphenol mono-acrylate, ortho acrylyl e nkeloe sebaka ke phenol le benzofuranone mekhahlelo e mengata.
Li-antioxidants tsa bisphenol monoacrylate:
Limolek'hule tsa bisphenol monoacrylate, carbon radical e nkoa ke sehlopha sa acrylyl, 'me li-radicals tsa enol tse hlahisoang li ka fetoloa li-radicals tse tsitsitseng tsa phenolic oksijene ke sehlopha se sebetsang sa hydroxyl ka molek'hule e tšoanang.Phello ena e tsejoa e le mokhoa o tsitsitseng oa ho tsitsisa lintho tse peli.Sena se fa bisphenol monoacrylate matla a matla haholo a ho tšoasa mahala.Ho tsitsisa ha eona ho matla esita le ka mocheso o phahameng.Likhamphani tsa Japane le Europe li hlahisitse lihlahisoa tse joalo.Hajoale, Sumilizer GM ka Sumitomo Chemical, IRGANOX 3052 ke BASF, le AO3352/AO3353 li sebelisoa haholo 'marakeng.
