Lintho tsa Lik'hemik'hale:

Styrene ke mokelikeli mochesong oa kamore, ha e na 'mala, e nang le monko o hlabang, styrene e ka cha, ntlha e belang ea likhato tse 145.2, ntlha ea leqhoa ea -30.6 likhato tsa Celsius, matla a khoheli a itseng 0.906, styrene ha e qhibilihe ka metsing, haeba e le likhato tse 25 tsa Celsius, styrene. solubility ke 0.066% feela. Styrene e ka tsoakoa le ether, methyl ferment, carbon disulfide, acetone, benzene, toluene le tetra-ironic carbon ka tekanyo efe kapa efe. Styrene ke solvent e ntle bakeng sa rabara ea tlhaho, rabara ea maiketsetso le metsoako e mengata ea tlhaho. Styrene e chefo, haeba 'mele oa motho o hema mouoane o mongata oa styrene o tla baka chefo. Tekanyo e lumelletsoeng ea styrene moeeng ke 0.1mg/L. Mouoane oa styrene le moea li tla etsa motsoako o phatlohang.

Kopo:

Styrene ke monomer ea bohlokoa ea rabara ea maiketsetso, likhomaretsi le polasetiki. [3,4,5] E sebelisetsoa ho qaptjoa ha rabara ea styrene butadiene le resin ea polystyrene, polyester glass fiber e matlafalitsoeng le liphahlo. E sebelisetsoa ho lokisa polystyrene, ion exchange resin, le foam polystyrene. E boetse e sebelisoa bakeng sa copolymerization le li-monomers tse ling ho hlahisa lipolasetiki tse fapaneng tsa boenjiniere, joalo ka copolymerization ea acrylonitrile le butadiene ho hlahisa resin ea ABS, e sebelisoang haholo lisebelisoa tse fapaneng tsa lapeng le liindasteri. Copolymerization e nang le acrylonitrile, e fumanoeng SAN ke resin e hanyetsanang le ho ts'oha le 'mala o khanyang. SBS e hlahisoang ke copolymerization le butadiene ke rabara ea thermoplastic, e sebelisoang haholo e le polyvinyl chloride le acrylic modifier. SBS le SIS thermoplastic elastomers li entsoe ka butadiene le isoprene copolymerization, 'me e le monoma ea crosslinking, styrene e sebelisoa ho fetola PVC, polypropylene, le polyester e sa tsitsang.
Syrene e sebelisoa e le monoma e thata bakeng sa tlhahiso ea styrene acrylic emulsion le sekhomaretsi se nang le khatello ea solvent. Sekhomaretsi sa emulsion le pente li ka lokisoa ka copolymerization ka vinyl acetate le acrylic ester. Styrene ke e 'ngoe ea li-vinyl monomers tse sebelisoang haholo lefapheng la saense, tse sebelisoang linthong tse fapaneng tse fetotsoeng le tse kopantsoeng.[6]
Ho phaella moo, palo e nyenyane ea styrene e boetse e sebelisoa e le litlolo le li-intermediate tse ling. Ka chloromethylation ea styrene, cinnamyl chloride e sebelisoa e le pheko bakeng sa qeto e matla ea bohloko bo sa thekeseleng, 'me styrene e boetse e sebelisoa e le moriana oa mantlha oa antitussive, expectorant le anticholinergic ka mpeng. E ka sebelisoa ho etsa li-intermediate tsa dae tsa anthraquinones, li-emulsifiers tsa chefo e bolaeang likokoanyana, le styrene phosphonic acids ore dressing agent le li-copper plating lighteners.
