Ikoreshwa mugukora reberi, plastike, na polymers.
a) Umusaruro wa: polystirene yaguka (EPS);
b) Umusaruro wa polystirene (HIPS) na GPPS;
c) Umusaruro wa styrenic co-polymers;
d) Umusaruro wa polyester idahagije;

f) Umusaruro wa styrene-butadiene latex;
g) Umusaruro wa styrene isoprene co-polymers;
h) Umusaruro wa styrene ishingiye kuri polymeric;
i) Umusaruro wa polyoli yuzuye.Styrene ikoreshwa cyane nka monomer mugukora polymers (nka polystirene, cyangwa reberi na latex)
Styrene maleic anhydride (SMA cyangwa SMAnh) ni polymer synthique yubatswe na styrene na monhyders ya manic.Monomers irashobora guhinduranya hafi rwose, bigatuma ihinduka cololymer, [1] ariko (random) copolymerisation ifite munsi ya 50% ya anhydride yumugabo nayo irashoboka.Polimeri ikorwa na polymerisiyonike ikabije, ikoresheje peroxide kama nkuwatangije.Ibintu nyamukuru biranga SMA copolymer ni isura yayo igaragara, irwanya ubushyuhe bwinshi, ituze ryinshi, hamwe nuburyo bwihariye bwamatsinda ya anhydride.Ibintu byanyuma bivamo ibisubizo bya SMA mubisubizo bya alkaline (bishingiye kumazi) no gutatanya.
SMA iraboneka murwego runini rwibipimo bya molekuline hamwe na anhydride ya kigabo (MA).Mubisanzwe bihuza iyo mitungo yombi, SMA irahari nka kirisiti isobanutse neza ishobora gukoreshwa muburyo butandukanye bwa porogaramu.SMA polymers ifite uburemere buke bwa molekile ikoreshwa cyane mubikorwa bya pulasitiki yubuhanga, mubisanzwe mubikorwa byahinduwe kandi fibre yibirahure byuzuye.Ubundi, SMA ikoreshwa ikoresheje transparency yayo ifatanije nibindi bikoresho bibonerana nka PMMA cyangwa ubushyuhe bwo kurwanya ubushyuhe bwongera ubushyuhe bwibindi bikoresho bya polymers nka ABS cyangwa PVC.Ubushobozi bwa SMA mubisubizo bya alkaline butuma bikwiranye nuburyo butandukanye mubijyanye nubunini (impapuro), binders, dispersants hamwe na coatings.Imyitwarire yihariye ya SMA ituma iba agent ikwiye yo guhuza mubisanzwe polymer zidahuye (urugero: ABS / PA ivanze) cyangwa guhuza.Ubushyuhe bwikirahure bwa Styrene maleic anhydride ni 130 - 160 ° C.
