Lub hauv paus ntsiab lus ntawm NVP Copolymerization
Cov qauv molecular ntawm NVP monomer muaj cov Vinyl qauv, uas yog qhov yooj yim rau cov tshuaj tiv thaiv polymerizer. Tsis tas li ntawd, NVP monomer tseem yooj yim heev rau copolymerize nrog lwm cov neeg tsis tau muaj txiaj ntsig muaj ob qho tib si nVP cov txheej txheem thiab lwm yam kev ntseeg monomer.
Feem ntau hais lus, kev ua tau zoo ntawm cov molecular hnyav copolymers yog nruab nrab ntawm copolymerized monomers, thiab kev ua haujlwm ntawm hybridizes tshwm sim ntawm cov homopolymers ntawm cov monomers uas yog nws. Los ntawm kev siv cov kev ua tau zoo ntawm NVP cov txheej txheem rau Copolymerize nVP monomers nrog lwm tus monomers, kev ua yeeb yam ntawm copolymers tuaj yeem sib xyaw cov yam ntxwv ntawm PVP thiab lwm cov polymers. Cov kev tshawb fawb ntawm Copolymerization ntawm Copolymerization ntawm Copolymerization ntawm Copolymerization Ntawm Copolymerization ntawm NVP nrog lwm cov Monomers thiab daim ntawv thov ntawm nws cov ntawv tshaj tawm muaj qhov tseem ceeb hauv qab no:
1. Cov pab pawg ua haujlwm ntawm cov qauv molecular ntawm cov qauv molecular ntawm lwm cov qauv kev ua haujlwm ntawm cov qauv moleces kom tau txais cov molecular hnyav copolymer nrog ntau pawg ua haujlwm. Cov copolymer no yuav tsis tau npaj txhij txog cov khoom thiab cov ntawv thov, thiab ua kom muaj peev xwm ua tau zoo, ua kom muaj peev xwm ua kom muaj peev xwm ntxiv, ua kom cov copolymers tsis muaj dej- soluble tsis muaj tshuaj.
2. Siv NVP kom txuas cov copolymerize nrog lwm cov polymers, thiab cov copolymer hloov pauv tau ua tau zoo dua thiab dav daim ntawv thov.
3. Siv cov neeg pheej yig tsis muaj peev xwm ua rau NVP, thiab hloov cov PvP kim nrog cov ntawv siv pheej yig yam tsis tau hloov cov nyhuv thov.
4. Txoj kev tshawb fawb ntawm Copolymerization ntawm NVP nrog lwm cov neeg tsis tau muaj kev ywj pheej, uas tuaj yeem txhawb kev kawm ntawm Copolymerization Kinetics.
Tsis tas li ntawd, kev kawm txog nvp copolymers tuaj yeem tuaj yeem nthuav tawm daim ntawv thov teb ntawm NVP thiab qhib txoj kev tshiab rau daim ntawv thov ntawm NVP.
Copolymerized monomers
Ntau cov neeg tsis txaus ntseeg nrog Vinyl qauv tuaj yeem ua NVP monomers, xws li vinyl acetate thiab vinyl supely, hydrocarbons xws li ethingre thiab styrene, thiab lwm yam.
Txawm hais tias muaj ntau NVP cov tub luam ntawv tuaj yeem tau txais los ntawm kev dawb radical polymerization, muaj tsuas yog ob peb uas yog pawg- tsim tawm hauv kev lag luam tam sim no. Ntawm lawv, Copolymerization ntawm NVP thiab Vinyl acetate yog qhov feem ntau siv.
Qauv copyymerization
Lub Copolymerization Ntawm NVP thiab Vacretization tuaj yeem nqa tawm los ntawm Polymerization, etconol, benzene, acetone, ethhans, tab sis lwm yam, tab sis lwm yam.
Yog hais tias cov cheebtsam ntawm txhua tus neeg comonomer hauv copolymer muaj sib txawv, cov khoom ntawm cov copolymer kuj txawv. Yog li, cov teeb meem tseem ceeb hauv synthesis ntawm synthesis ntawm synthesis ntawm synthesis ntawm nvp copolymers yog los tswj qee cov txheej txheem copolymerization kom muaj pes tsawg tus txheej txheem ntawm copolymer nyob rau qee qhov ntau. Feem ntau hais lus, nyob rau hauv polymerization engineering, muaj ob txoj hauv kev los tswj cov kab mob tswj hwm, thiab txiav cov tshuaj tiv thaiv kev tsim nyog: ib qho yog cov tshuaj tiv thaiv polymerization thaum cov tshuaj ntsuam copolymerization ncav cuag. Hom no yog qhov tsim nyog rau cov tshuab nrog cov nkhaus tiaj tus nkhaus ntawm cov copolymer muaj pes tsawg leeg thiab ntsuas dua; Qhov thib ob yog siv cov txheej txheem pub mis, uas yog, kom ntxiv nrawm {3} {{} reacting monomers rau polymerization. Hom qauv no yog qhov haum rau cov tshuab nrog txoj kab nqes loj ntawm qhov nkhaus loj ntawm cov copolymer thiab tus nqi hloov dua siab tshiab. Yog li ntawd, thaum kawm cov tshuaj tiv thaiv Copolymerizer ntawm NVP, nws yog ib qho tseem ceeb kom nkag siab cov kev sib piv thiab cov nyiaj luam ntawv copolymerization tas li txhua tus monomer.
