Ibihebujijwe bibangamiye hamwe na tert-Butyl (x = tet-Buyl) na methyl (r = methyl ch3) kuri o-star ya hydroxyl yitsinda ryibitekerezo ingaruka. Iyi miterere mishya ya dehenol antioxident yitwa asimmetric ibangamira indwara ya pentioxside.
Asimmetric ibangamira imiterere ya dehelic hamwe nitsinda rya tert-Butyl hamwe nitsinda rya methyl kuri hydroxyl ortho-umwanya birahagije kugirango twirinde. Asimmetric ibangamira antiolidant penolicant, hamwe na 2 - methyl - 6 - Ikibuto cya Tertiary Ifite rero imiti igaragara kuruta ubwoko gakondo bwa symmetcical bwanga phenol, kandi bubereye porogaramu yubushyuhe.
AN245, AN1790 (kimwe na AN2777) na Ao80 nibisanzwe bitatu bikunze kugaragara ndwara antiolidants, muri zo AN245 ikoreshwa cyane hamwe nigiciro gito.
245 birakwiriye cyane cyane gutegurika antiolic infashanyo ya polymenti kama. Nka antioxidant, ikoreshwa muguhuza no kwikuramo ubushyuhe bwa syrrene nko mu kibuno, mbs na abs, plastics incuro nka pi na polyurethane. Numurongo mwiza wurugani muburyo bwa PVC. Iki gicuruzwa ntigifite ingaruka kuri polymer reaction, zikoreshwa hejuru ya polystyrene, chlowstyrene, chloride ya polyviny, irashobora kongerwa kuri monomer mbere ya polymeization.
Usibye uburyo bwo gutanga ifu isanzwe, turashobora gutanga 35% ibirimo byo gutatanya-AN245DW. Nyuma yimyaka myinshi yuburambe bwumusaruro, gutatanya amazi yakozwe kandi bitangwa na sosiyete yacu ntabwo byoroshye kurenganya, kandi biroroshye gutandukana kuruta ifu, nicyo Antioxidant ikoreshwa muburyo bwa PVC.
