Meatotino tau vailaau:

Styrene o se vai i le vevela o le potu, e leai se lanu, ma se manogi manogi, styrene e mu, vevela vevela 145.2 tikeri Celsius, malulu tulaga o -30.6 tikeri Celsius, mamafa patino 0.906, styrene e le mafai ona solu i le vai, pe afai i le 25 tikeri Celsius, styrene. solubility e na'o le 0.066%. Styrene e mafai ona faʻafefiloi ma eter, methyl ferment, carbon disulfide, acetone, benzene, toluene ma tetra-ironic carbon i soʻo se vaega. Styrene ose solvent lelei mo pa'u fa'anatura, pa'u gaosia ma le tele o mea fa'aola. E oona le Styrene, pe afai e tele naua le ausa o le styrene e manavaina e le tino o le tagata. Ole fa'ataga ole styrene ile ea ole 0.1mg/L. Styrene ausa ma le ea o le a fausia ai se paluga papa.

Talosaga:

Styrene o se monomer taua o pa'u gaosia, pipii ma palasitika. [3,4,5] E faʻaaogaina mo le tuʻufaʻatasia o le styrene butadiene paʻu ma le polystyrene resin, polyester glass fiber faʻamalosia palasitika ma coatings. E faʻaaogaina mo le sauniaina o le polystyrene, resin exchange ion, ma le foam polystyrene. E faʻaaogaina foʻi mo le kopiina ma isi monomers e gaosia ai palasitika faʻainisinia eseese, e pei o le copolymerization o le acrylonitrile ma le butadiene e maua ai le resini ABS, faʻaaogaina lautele i meafale eseese ma alamanuia. Copolymerization ma acrylonitrile, maua SAN o se resin ma teteʻe tetee ma lanu susulu. O le SBS na gaosia e le copolymerization ma le butadiene o se pa'u thermoplastic, lea e masani ona faʻaaogaina e avea o se polyvinyl chloride ma acrylic modifier. SBS ma SIS thermoplastic elastomers e faia i le butadiene ma isoprene copolymerization, ma o se monomer crosslinking, styrene e faʻaaogaina i le fesuiaiga o le PVC, polypropylene, ma le polyester unsaturated.
Syrene o loʻo faʻaaogaina e avea o se monomer faigata mo le gaosiga o le styrene acrylic emulsion ma le faʻapipiʻiina o le mamafa o le soli. Emulsion adhesive ma vali e mafai ona saunia e copolymerization ma vinyl acetate ma acrylic ester. Styrene o se tasi o monomers vinyl e masani ona faʻaaogaina i le matata faʻasaienisi, faʻaaogaina i mea eseese faʻaleleia ma tuʻufaʻatasia.[6]
E le gata i lea, o se vaega itiiti o le styrene o loʻo faʻaaogaina foi e fai ma mea manogi ma isi mea vavalalata. E ala i le chloromethylation o le styrene, o le cinnamyl chloride o loʻo faʻaaogaina e avea o se mea vavalo mo le faʻamaʻi e leai se faʻamaʻi faʻamaʻi tiga malosi, ma o le styrene o loʻo faʻaaogaina foi o se antitussive, expectorant ma anticholinergic uluai vailaau i le manava Changning. E mafai ona faʻaaogaina e faʻapipiʻi ai le anthraquinones dye intermediates, pesticide emulsifiers, ma styrene phosphonic acids ore dressing agent ma apamemea faʻamalama.
