Qee cov polymers yog tsim los ntawm condensation polymerization. Nyob rau hauv condensation polymerization, ib tug me me molecule yog tsim raws li ib tug los ntawm cov khoom txhua lub sij hawm ib daim ntawv cog lus tsimntawm ob monomers. Cov molecule me no feem ntau yog dej. Ib qho piv txwv ntawm condensation polymer yog nylon.
Dab tsi yog ob lub monomers rau lub condensation polymer?
A polyester cov ntaub ntawv los ntawm ob hom monomers: ib 'dicarboxylic acid' uas muaj ob pawg carboxylic acid, - COOH . a 'diol' uas muaj ob pawg cawv, -OH.
Dab tsi yuav tsum muaj ob lub monomers muaj sib xws rau condensation polymerization tshwm sim?
Ntxiv rau polymerization, cov monomers yuav tsum muaj C=C ob daim ntawv cog lus. Txawm li cas los xij, hauv condensation polymerization, cov monomers tsis xav tau C=C ob daim ntawv cog lus tab sis lawv xav tau ob pawg ua haujlwm.
YPuas condensation ua ke polymers los ua monomers?
Muaj ob peb txoj hauv kev monomers ua ke los ua cov polymers ntawm cov yas. Hauv cov tshuaj tiv thaiv condensation, ob lub molecules ua ke nrog qhov poob ntawm cov molecule me, feem ntau yog dej, cawv lossis kua qaub. …
Puas cov tshuaj tiv thaiv condensation koom nrog monomers?
Macromolecules yog tsim los ntawm ib chav tsev hu ua monomers uas tau koom nrog covalent bonds los tsim cov polymers loj. … Ib lub monomer koom nrog lwm tus monomer nrog kev tso tawm ntawm cov dej molecule, uas ua rau tsim kom muaj covalent daim ntawv cog lus. Cov tshuaj tiv thaiv no yog hu ua dehydration lossis condensation reactions.
