ʻO ka polymer ka mea maʻamau i kahi kūlana anoxic ma lalo o nā kūlana hoʻoponopono extrusion, a aia ka ʻōnaehana i ka nui o nā kalapona kalapona ma mua o nā radical alkoxy a me nā radical hydroxyl.No laila, pono e hiki i ka stabilizer kaʻina hana kūpono ke hopu i nā radical manuahi me ka maikaʻi.ʻO ka antioxidant hydroxylamine i ʻōlelo ʻia ma luna nei he ʻano mea hoʻopaʻa kalapona kalapona.
ʻO ka nui o ka carbon free radical trapping agents i ka mākeke he hydroxylamine, bisphenol mono-acrylate, ortho acrylyl substituted phenol a me benzofuranone kekahi mau ʻano.
Bisphenol monoacrylate antioxidants:
I loko o nā molekele bisphenol monoacrylate, ua hopu ʻia ke kalapona kalapona e ka hui acrylyl, a hiki ke hoʻololi ʻia nā radical enol i nā radical phenolic oxygen paʻa e ka hui hana hydroxyl i loko o ka mole like.ʻIke ʻia kēia hopena ma ke ʻano he bifunctional stabilization mechanism.Hāʻawi kēia i ka bisphenol monoacrylate i kahi mana hoʻopaʻa radical manuahi ikaika loa.He ikaika kona hoʻokūpaʻa ʻana i nā wela kiʻekiʻe.Ua hoʻolaha nā ʻoihana ma Iapana a me ʻEulopa i nā huahana like.I kēia manawa, hoʻohana nui ʻia ʻo Sumilizer GM e Sumitomo Chemical, IRGANOX 3052 e BASF, a me AO3352/AO3353 i ka mākeke.
