Ngā Āhuatanga matū:

Ko Styrene tetahi puhui matū waro kei a ia te tauira matū C8H8 me te tauira hanganga CH2=CHC6H5, e mohiotia ana ko styrol, vinylbenzene, phenylethene,phenylethylene,styrene,styreen me era atu.Ko tona hanganga matū he whakakai benzene kua herea ki te roopu vinyl.I te pāmahana me te pehanga o te rūma, he wai maamaa, he kore tae te styrene.Ko te Styrene he monomer nui o te rapa waihanga, te whakapiri me te kirihou, penei i te pepa styrene.

Taupānga:

Ko te Styrene he monomer nui o te rapa waihanga, te whakapiri me te kirihou.[3,4,5] Ka whakamahia mo te whakahiatotanga o te rapa styrene butadiene me te kapia polystyrene, te muka karaihe polyester hei whakakaha i nga kirihou me nga paninga.Ka whakamahia mo te whakarite i te polystyrene, te kapia whakawhiti katote, me te polystyrene pahuka.Ka whakamahia ano hoki mo te kape me etahi atu monomers ki te whakaputa i nga momo kirihou miihini, penei i te copolymerization o te acrylonitrile me te butadiene ki te whakaputa kapia ABS, e whakamahia nuitia ana i roto i nga momo taputapu whare me nga umanga.Ko te Copolymerization me te acrylonitrile, kua riro ko SAN he kapia me te awangawanga ohorere me te tae kanapa.Ko te SBS i puta mai i te copolymerization me te butadiene he rapa thermoplastic, e whakamahia whanuitia ana hei polyvinyl chloride me te whakarereke kiriaku.Ko te SBS me te SIS thermoplastic elastomers he mea hanga ki te copolymerization butadiene me te isoprene, a hei monomer honohono, ka whakamahia te styrene ki te whakarereke i te PVC, te polypropylene, me te polyester haunga.
whakamahia Syrene te rite te monomer pakeke mo te hanga o te whakaehunga kiriaku styrene me te pehanga whakarewa whakapiri tairongo.Ka taea te whakarite i te whakapiri whakaehunga me te peita ma te kapolymerization me te acetate vinyl me te hākawa kiriaku.Ko Styrene tetahi o nga monomers vinyl e whakamahia nuitia ana i roto i te mara putaiao, e whakamahia ana i roto i nga momo mea whakarereke me nga mea hiato.[6]
I tua atu, ka whakamahia ano te iti o te styrene hei hinu kakara me etahi atu takawaenga.Na roto i te chloromethylation o te styrene, ka whakamahia te cinnamyl chloride hei takawaenga mo te whakatau mamae mamae kore anesthetic analgesic, ka whakamahia ano te styrene hei rongoa antitussive, expectorant me anticholinergic taketake i roto i te kopu Changning.Ka taea te whakamahi ki te whakahiato i nga takawaenga waikano anthraquinones, whakaemulsifiers pesticide, me te styrene phosphonic acids ore dressing agent me te whakakikorua parahi.
