Ntxiv cov polymers Piv txwv li: Ethylene dhau los ua polymerization los ua polythene. Cov mis empirical ntawm monomer thiab polymer yog tib yam. Lwm cov piv txwv: … Styrene-butadiene roj hmab yog ib qho ntxiv polymer tsim los ntawm ntxiv cov tshuaj tiv thaiv ntawm butadienethiab styrene.
Lub tebchaw twg tuaj yeem nkag mus ntxiv polymerization?
1.2.
Nyob rau hauv cov txheej txheem polymerization no, cov polymers ntxiv tau npaj los ntawm monomers yam tsis muaj cov khoom me me. Feem ntau, unsaturated monomers xws li olefins, acetylenes, aldehydes, los yog lwm yam tebchawundergo ntxiv polymerization.
Yuav ua li cas cov polymer tsis tuaj yeem ua ntxiv polymerization?
2. Dab tsi ntawm cov hauv qab no tsis tuaj yeem raug ntxiv polymerization? Kev piav qhia: Cov monomers koom nrog ntxiv polymerisation yog cov tsis muaj qhov sib xyaw xws li alkenes thiab alkadienes. Qhov no yog vim nws tsis koom nrog kev tshem tawm ntawm ib qho molecule thiab li no yuav tsum tau rhuav tshem ntawm ob daim ntawv cog lus kom nws ua tiav.
YPuas yog PVC ib qho ntxiv polymer?
Cov khoom siv ntxiv uas muaj ntau tshaj plaws yog polyolefins, piv txwv li polymers muab los ntawm kev hloov pauv ntawm olefins (alkenes) mus rau cov saw ntev alkanes. … Piv txwv ntawm xws li polyolefins yog polyethenes, polypropylene, PVC, Teflon, Buna rubbers, polyacrylates, polystyrene, thiab PCTFE.
Yuav ua li cas ntxiv polymerization?
Ntxiv polymerizationCov tshuaj tiv thaiv ntxiv uas muaj ntau ntawm cov me me molecules (monomers) koom ua ke los tsim cov molecules loj heev (polymers). … Alkenes yog cov monomers tshwj xeeb uas muaj txiaj ntsig zoo vim tias lawv muaj ob daim ntawv cog lus thiab tuaj yeem ua rau muaj kev cuam tshuam ntxiv ntawm lawv tus kheej.
