Ngā Āhuatanga matū:

He wai te Styrene i te pāmahana rūma, he kore tae, he kakara reka, he muramura te styrene, te ira koropupu 145.2 nga nekehanga Celsius, te ira mīti o -30.6 nga nekehanga Celsius, te taumaha motuhake 0.906, karekau e rewa te styrene ki te wai, mena kei te 25 nga nekehanga Celsius, styrene he 0.066% anake te whakarewatanga. Ka taea te konatunatua a Styrene ki te ether, te methyl ferment, te waro disulfide, te acetone, te benzene, te toluene me te waro tetra-ironic ahakoa te rahinga. He whakarewa pai a Styrene mo te rapa maori, te rapa waihanga me te maha o nga puhui waro. He paitini te Styrene, ki te nui rawa te hongi a te tinana o te tangata i te kohu styrene ka paona. Ko te kukū o te styrene i roto i te rangi he 0.1mg/L. Ko te kohu styrene me te hau ka hanga he ranunga pahū.

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.
