Ib qho ntxiv polymer yog ib qho polymer uas tsim los ntawm kev sib txuas yooj yim ntawm monomers yam tsis muaj kev sib koom ua ke ntawm lwm yam khoom. Ntxiv polymerization txawv ntawm condensation polymerization, uas ua ke tsim cov khoom, feem ntau yog dej.
Dab tsi ntxiv polymerization nrog piv txwv?
Ntxiv cov polymers suav nrog polystyrene, polyethylene, polyacrylates, thiab methacrylates. Condensation polymers yog tsim los ntawm cov tshuaj tiv thaiv ntawm bi- los yog polyfunctional molecules, nrog tshem tawm ntawm ib co me me molecule (xws li dej) raws li ib tug by-product. Piv txwv xws li polyester, polyamide, polyurethane, thiab polysiloxane.
txhais li cas los ntawm kev ntxiv polymerization?
Nyob hauv polymerization. Ntxiv rau polymerization, monomers hnov qab tsim cov polymer yam tsis muaj kev tsim los ntawm cov khoom. Ntxiv cov polymerizations feem ntau yog ua nyob rau hauv lub xub ntiag ntawm catalysts, uas nyob rau hauv tej rooj plaub exert tswj cov txheej txheem cov ntsiab lus uas muaj ib qho tseem ceeb los ntawm cov khoom ntawm lub polymer.
Dab tsi yog qhov sib ntxiv thiab condensation polymerization?
Ntxiv polymerization yog txheej txheem ntawm rov ntxiv ntawm monomers uas muaj ob lossis peb daim ntawv cog lus los tsim cov polymers. Condensation polymerization yog txheej txheem uas muaj kev rov ua kom rov ua kom rov zoo dua ntawm ob qhov sib txawv bi-functional lossis tri-functional monomers.
Ib qho ntawm cov hauv qab no yog piv txwv ntawm cov polymer ntxiv?
Neoprene thiabTeflonyog tsim los ntawm kev ntxiv polymerization thaum terylene thiab nylon-6, 6 yog tsim los ntawm condensation polymerization.
