I-Styrene maleic anhydride (i-SMA okanye i-SMAnh) yipolymer eyenziweyo eyakhiwe nge-styrene kunye ne-maleic anhydride monomers.Iimonomers zingaphantse zitshintshe ngokugqibeleleyo, ziyenze icopolymer etshintshanayo, [1] kodwa (ngokungaqhelekanga) i-copolymerization engaphantsi kwe-50% yomxholo we-anhydride ye-maleic nayo inokwenzeka.Ipolymer yenziwa yi-polymerization ye-radical, isebenzisa i-organic peroxide njengomqalisi.Iimpawu eziphambili ze-SMA copolymer kukubonakala kwayo ekuhleni, ukumelana nobushushu obuphezulu, uzinzo oluphezulu, kunye nokuphinda kusebenze kwakhona kwamaqela e-anhydride.Uphawu lokugqibela lubangela ukunyibilika kwe-SMA kwizisombululo ze-alkaline (ezisekelwe emanzini) kunye nokusasazwa.
I-SMA ifumaneka kuluhlu olubanzi lobunzima beemolekyuli kunye nemixholo ye-anhydride ye-maleic (MA).Kudibaniso oluqhelekileyo lwezo zakhiwo zimbini, i-SMA ifumaneka njengekristale ecacileyo yegranule enokusetyenziswa kwiintlobo ngeentlobo zezicelo.Iipholima ze-SMA ezinobunzima obuphezulu bemolekyuli zisetyenziswa kakhulu kubunjineli bezicelo zeplastiki, ngokwesiqhelo kwimpembelelo elungisiweyo kunye nokhetho olukhethiweyo lwefiber yeglasi ezaliswe ukwahluka.Kungenjalo, i-SMA isetyenziswa kusetyenziswa ukungafihli kwayo kudityaniswe nezinye izinto ezibonakalayo ezifana ne-PMMA okanye ukuxhathisa ubushushu ekunyuseni ubushushu kwezinye izinto zepolima ezifana ne-ABS okanye i-PVC.I-solubility ye-SMA kwizisombululo ze-alkaline yenza ukuba ifaneleke kwizicelo ezahlukeneyo kwintsimi yokulinganisa (iphepha), i-binders, i-dispersants kunye neengubo.I-reactivity ethile ye-SMA iyenza i-arhente efanelekileyo yokuhambelana neepolymers eziqhelekileyo ezingahambelaniyo (umz. i-ABS/PA blends) okanye i-cross-linking.Ubushushu beglasi benguqu ye-Styrene maleic anhydride yi-130 - 160 °C.
