Propene tau dhau ntxiv polymerizationlos tsim cov poly (propene), feem ntau hu ua polypropylene, uas yog ib qho ntawm ntau yam thermoplastic polymers muaj kev lag luam. Kev sib xyaw ntawm propene thiab lwm yam monomers tsim ntau yam ntawm cov khoom tseem ceeb co-polymer.
Koj ua li cas polymerize ib alkene?
Cationic Polymerization Ua ntej, ib qho proton los ntawm cov kua qaub uas tsim nyog ntxiv rau alkene kom tawm los ntawm carbocation. Tom qab ntawd, thaum tsis muaj lwm yam muaj zog nucleophilic reagent, lwm cov alkene molecule pub rau ib khub electron thiab tsim cov saw hlau ntev dua.
YPuas propene ua monomer?
Cov monomers siv los ua lwm yam ntxiv polymers yog kos rau hauv ib qho zoo sib xws rau ethene, piv txwv li, propene. Txawm hais tias qhov no yog txoj hauv kev niaj hnub los kos cov qauv qauv rau propene, rau lub hom phiaj ntawm kev qhia yuav ua li cas cov molecule ua raws li ib tug monomer thiab tsim tau ib tug polymer nws yuav tsum tau kos rau hauv ib txoj kev sib txawv.
Dab tsi alkene siv los ua polyethylene?
The ethene thiab propene yog cov ntaub ntawv tseem ceeb rau kev ua cov yas lossis ua lwm yam tshuaj lom neeg. Koj yuav nco ntsoov tias thaum lub sij hawm polymeriation ntawm ethene, ntau txhiab ethene molecules koom ua ke los ua poly (ethene) - feem ntau hu ua polythene.
polyethylene siv rau dab tsi?
Low-density polyethylene
Nws melting point yog kwv yees li 110 ° C (230 ° F). Cov thawj coj siv yog nyob rau hauv ntim zaj duab xis,Cov hnab khib nyiab thiab khoom noj khoom haus, ua liaj ua teb mulch, xaim thiab cable rwb thaiv tsev, nyem fwj, khoom ua si, thiab khoom siv hauv tsev.
