Qhov sib txawv tseem ceeb ntawm copolymer thiab condensation polymer yog tias cov copolymers tsim los ntawm copolymerization whereas condensation polymers tsim los ntawm condensation tshua.
A polymer yog ib qho loj, macromolecule uas muaj ntau txhiab tus rov ua dua tshiab txuas rau ib leeg los ntawm covalent tshuaj sib txuas. Muaj ntau ntau hom polymers. Peb tuaj yeem faib lawv raws li cov qauv, morphology, khoom, thiab lwm yam. Copolymers thiab condensation polymers yog ob hom.
Copolymer yog dab tsi?
A copolymer yog cov khoom siv polymer uas muaj ntau dua ib hom kev rov ua dua tshiab. Yog li, ob lossis ntau hom monomers txuas nrog ib leeg hauv kev tsim cov copolymer. Thiab, cov txheej txheem ntawm polymerization uas tsim ib copolymer yog "copolymerization". Yog tias qhov copolymerization no suav nrog ob hom monomers, tom qab ntawd cov khoom siv polymer uas tshwm sim yog bipolymer. Ib yam li ntawd, yog tias nws muaj peb lub monomers, ces nws ua rau terpolymer, thiab yog tias muaj plaub monomers, ces nws ua rau quaterpolymer. Feem ntau cov txheej txheem loj hlob polymerization ua rau cov copolymer.

Tsis tas li, muaj ntau hom copolymers raws li cov qauv ntawm cov khoom siv polymer. Linear copolymers suav nrog cov hauv qab no:
- Block copolymer - muaj ob lossis ntau dua homopolymer subunits txuas rau ib leeg ntawm covalent bonds.
- Alternating copolymer - muaj cov qauv hloov pauv tsis tu ncua ntawm ob lub monomers sib txawv hauv cov qauv kab.
- Lub sijhawm copolymers - muaj cov chav nyob hauv ib ntus rov ua dua.
- Gradient copolymer - cov monomer muaj pes tsawg leeg hloov maj mam raws cov saw.
Ib yam li ntawd, muaj cov qauv tsim ntawm cov copolymer ib yam nkaus. Piv txwv xws li txhuam thiab txhuam copolymer. Tsis tas li ntawd, muaj copolymer graft. Nws muaj nws cov saw tseem ceeb uas muaj tib hom monomer units thiab nws cov ceg ua los ntawm cov monomer sib txawv.
YCondensation Polymer yog dab tsi?
Condensation polymer yog cov khoom siv polymer uas tsim los ntawm cov tshuaj tiv thaiv condensation. Cov tshuaj tiv thaiv no cuam tshuam nrog kev sib koom ua ke ntawm cov molecules nrog ib leeg thaum tshem tawm cov khoom lag luam xws li dej molecules, methanol molecules, thiab lwm yam. Vim tias cov tshuaj tiv thaiv no tsim cov polymer, peb tuaj yeem hu nws ua polycondensation. Ntxiv mus, nws yog ib daim ntawv ntawm cov kauj ruam-loj hlob polymerization.
Daim duab 02: Tsim cov Condensation Polymer
Nyob rau hauv cov txheej txheem no, ib tug linear polymer cov ntaub ntawv los ntawm monomers uas muaj ob pawg ua hauj lwm nyob rau hauv tib molecule. Piv txwv li, cov tebchaw nrog ob pawg reactive kawg tuaj yeem dhau qhov polymerization.
Ntxiv mus, cov khoom siv polymer feem ntau muaj xws li polyamides, polyacetals, proteins, thiab lwm yam. Tsis tas li ntawd, cov polymers no yog biodegradable dua li lwm hom polymers. Tshwj xeeb tshaj yog, nyob rau hauv lub xub ntiag ntawm catalysts los yog cov kab mob enzymes, cov polymers undergo hydrolysis.
Qhov txawv ntawm Copolymer thiab Condensation Polymer yog dab tsi?
Txawm tias ob qho tib si copolymer thiab condensation polymers tuaj yeem tsim los ntawm cov txheej txheem kev loj hlob ntawm cov txheej txheem polymerization; qee copolymers tsim los ntawm saw-loj hlob polymerization ib yam nkaus. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm copolymer thiab condensation polymer. Txawm li cas los xij, peb npe cov txheej txheem ntawm kev tsim cov ntaub ntawv polymer sib txawv, qhia txog cov khoom kawg. Yog li, qhov sib txawv tseem ceeb ntawm copolymer thiab condensation polymer yog cov copolymers tsim los ntawm copolymerization whereas condensation polymers tsim los ntawm condensation tshua.
Raws li lwm qhov sib txawv tseem ceeb ntawm copolymer thiab condensation polymer, peb tuaj yeem hais tias copolymers muaj ntau hom monomers thaum condensation polymers tuaj yeem muaj tib hom monomers lossis ntau hom monomers.
Summary – Copolymer vs Condensation Polymer
Copolymers yog cov khoom siv polymer uas muaj tsawg kawg yog ob hom monomers. Ntawm qhov tod tes, condensation polymers yog cov ntaub ntawv polymer uas tsim los ntawm cov tshuaj tiv thaiv condensation thaum tshem tawm cov molecule me me raws li cov khoom lag luam. Qhov sib txawv tseem ceeb ntawm copolymer thiab condensation polymer yog cov copolymers tsim los ntawm copolymerization whereas condensation polymers tsim los ntawm condensation tshua.
