Styrene bụ mmiri mmiri n'ime ụlọ okpomọkụ, enweghị agba, na-esi ísì ụtọ, styrene na-ere ọkụ, ebe na-esi ísì ụtọ 145.2 degrees Celsius, ebe na-ekpo ọkụ nke -30.6 degrees Celsius, kpọmkwem ike ndọda 0.906, styrene na-adịghị ike na mmiri, ma ọ bụrụ na 25 degrees Celsius, styrene. Solubility bụ naanị 0.066%. Enwere ike ịgwakọta Styrene na ether, ferment methyl, carbon disulfide, acetone, benzene, toluene na tetra-iron carbon n'ụzọ ọ bụla. Styrene bụ ihe mgbaze dị mma maka roba eke, roba sịntetik na ọtụtụ ogige organic. Styrene bụ ihe na-egbu egbu ma nwee ike ịkpata nsị ma ọ bụrụ na ahụ mmadụ na-ekunye oke ikuku styrene. Ntinye uche nke styrene na ikuku bụ 0.1mg / L. Uzuoku Styrene na ikuku ga-emepụta ngwakọta mgbawa.

Styrene bụ monomer dị mkpa nke roba sịntetik, adhesives na plastik. [3,4,5] A na-eji ya eme ihe maka njikọ nke styrene butadiene roba na polystyrene resin, polyester glass fiber mesikwuru plastik na mkpuchi. A na-eji ya maka ịkwadebe polystyrene, resin mgbanwe ion, na polystyrene foam. A na-ejikwa ya maka copolymerization na monomers ndị ọzọ iji mepụta plastik injinịa dị iche iche, dị ka copolymerization nke acrylonitrile na butadiene iji mepụta resin ABS, nke a na-ejikarị na ngwa ụlọ na ụlọ ọrụ dị iche iche. Copolymerization na acrylonitrile, nwetara SAN bụ resin nwere ujo na-eguzogide na agba na-egbuke egbuke. SBS nke copolymerization na butadiene mepụtara bụ roba thermoplastic, nke a na-ejikarị eme ihe dị ka polyvinyl chloride na acrylic modifier. A na-eme SBS na SIS thermoplastic elastomers na butadiene na isoprene copolymerization, na dị ka monomer na-agafe agafe, a na-eji styrene mee ihe na mgbanwe nke PVC, polypropylene, na polyester na-adịghị mma.
A na-eji Syrene dị ka monomer siri ike maka mmepụta nke emulsion styrene acrylic na nrapado mmetụta mgbaze. Emulsion nrapado na agba nwere ike kwadebere site copolymerization na vinyl acetate na acrylic ester. Styrene bụ otu n'ime vinyl monomers ndị a na-ejikarị eme ihe na ngalaba sayensị, nke a na-eji n'ụdị dị iche iche gbanwetụrụ na ihe mejupụtara.[6].
Tụkwasị na nke ahụ, a na-ejikwa obere styrene dị ka ihe na-esi ísì ụtọ na ndị ọzọ dị n'etiti. Site na chloromethylation nke styrene, a na-eji cinnamyl chloride mee ihe dị n'etiti maka mkpebi mgbu na-adịghị anestetiiki analgesic siri ike, a na-ejikwa styrene dị ka ọgwụ antitussive, expectorant na anticholinergic mbụ na afọ na-agbanwe. Enwere ike iji ya na-emepụta ihe ndị na-esiji ihe anthraquinones, emulsifiers pesticide, na styrene phosphonic acid ore na ihe mgbakwasa ọla kọpa.
