PVC yog ua los ntawm cov dawb-radical polymerization hauv kev ncua. Lub monomer (bp 259 K) yog polymerized nyob rau hauv aqueous dispersion ntawm 325-350 K. Siab (13 atm) yog siv los khaws cov monomer nyob rau hauv ib theem ua kua. Txhawm rau tswj cov polymerization, xav tau ib tus pib.
Yuav ua li cas cov saw hlau polymer tsim?
Y A polymer yog ib qho loj molecule ua los ntawm me me, sib koom ua ke molecules hu ua monomers. … Monomers koom ua ke los ua cov saw hlau polymer los ntawm
ua covalent bonds- uas yog, los ntawm kev sib koom electrons. Lwm daim ntawv cog lus ces tuav cov pab pawg ntawm cov saw hlau ua ke los tsim cov khoom siv polymer.
Dab tsi monomer ua rau poly chloroethene?
Thiab piav qhia yuav ua li cas monomer molecules tsim cov polymer molecules. Qhia luv luv piav qhia txog lub ntsiab lus ntawm cov npe hydrocarbon thiab cov npe polymers li cas. Lo lus teb yog li ntawd, chloroethene.
YYuav ua li cas polymer yog tsim los ntawm chloroethene?
PVC yog tsim los ntawm polymerization ntawm vinyl chloride (chloroethene) uas yog nws tus kheej tsim los ntawm chlorination ntawm ethene.
Vim li cas chloroethene tuaj yeem dhau los ua polymer?
Poly(chloroethene) yog tsim los ntawm polymerising chloroethene, CH2=CHCl. … Poly (chloroethene) feem ntau yog amorphous nrog tsuas yog thaj chaw me me ntawm crystallinity Cov khoom thiab siv. Koj ib txwm cia siab tias amorphous polymers yuav hloov tau ntau dua li cov crystalline vim tias lub zog ntawm kev nyiam ntawm cov chains zoo li tsis muaj zog.
