Chemical Properties:

I-styrene ingxube yamakhemikhali ephilayo enefomula yamakhemikhali engu-C8H8 kanye nefomula yesakhiwo CH2=CHC6H5, eyaziwa nangokuthi i-styrol, i-vinylbenzene, i-phenylethene, i-phenylethylene, i-styrene, i-styreen njalonjalo. Isakhiwo sayo samakhemikhali sakhiwe indandatho ye-benzene ehlanganiswe eqenjini le-vinyl. Ezingeni lokushisa lekamelo nokucindezela, i-styrene iwuketshezi olucacile, olungenambala. I-styrene iyi-monomer ebalulekile yerabha yokwenziwa, izinamathiselo namapulasitiki, njengeshidi le-styrene.

Isicelo:

I-styrene iyi-monomer ebalulekile yerabha yokwenziwa, izinamathiselo namapulasitiki. [3,4,5] Isetshenziselwa ukuhlanganiswa kwerabha ye-styrene butadiene ne-polystyrene resin, i-polyester glass fiber eqinisiwe amapulasitiki kanye nezingubo. Isetshenziselwa ukulungisa i-polystyrene, i-ion exchange resin, ne-foam polystyrene. Iphinde isetshenziselwe i-copolymerization namanye ama-monomers ukukhiqiza amapulasitiki wobunjiniyela ahlukahlukene, njenge-copolymerization ye-acrylonitrile ne-butadiene ukukhiqiza i-ABS resin, esetshenziswa kabanzi ezintweni zikagesi zasendlini nezimboni ezahlukahlukene. I-Copolymerization ene-acrylonitrile, etholwe i-SAN iyinhlaka ekwazi ukumelana nokushaqeka nombala ogqamile. I-SBS ekhiqizwa yi-copolymerization nge-butadiene iyirabha ye-thermoplastic, esetshenziswa kabanzi njenge-polyvinyl chloride ne-acrylic modifier. I-SBS kanye ne-SIS thermoplastic elastomers enziwe nge-butadiene ne-isoprene copolymerization, futhi njenge-monomer exhumanisayo, i-styrene isetshenziselwa ukuguqulwa kwe-PVC, i-polypropylene, ne-polyester engasetshenzisiwe.
I-Syrene isetshenziswa njenge-monomer eqinile ekukhiqizeni i-styrene acrylic emulsion kanye ne-adhesive ebucayi yokucindezela kwe-solvent. Ukunamathela kwe-emulsion nopende kungalungiswa nge-copolymerization nge-vinyl acetate ne-acrylic ester. I-styrene ingenye yama-vinyl monomers asetshenziswa kakhulu emkhakheni wesayensi, esetshenziswa ezintweni ezihlukahlukene eziguquliwe nezihlanganisiwe.[6]
Ngaphezu kwalokho, inani elincane le-styrene libuye lisetshenziswe njengamakha kanye nezinye izinto eziphakathi. Nge-chloromethylation ye-styrene, i-cinnamyl chloride isetshenziswa njengesithako esimaphakathi sokunqunywa kobuhlungu obunamandla obungeyona i-anesthetic, futhi i-styrene iphinde isetshenziswe njengomuthi wokuqala oqeda ukuvuvukala, we-expectorant kanye ne-anticholinergic ekuguqukeni kwesisu esiswini. Ingasetshenziselwa ukuhlanganisa ama-anthraquinones odayi abaphakathi, ama-emulsifiers wezibulala-zinambuzane, kanye ne-styrene phosphonic acids ore dressing agent kanye nezikhanyisi ze-copper plating.
