PVP kuj tseem siv dav ua qhov tsis sib haum thiab nplaum, thiab tseem tuaj yeem siv rau daim tawv nqaij zom zom thiab ua kom lub raum lim ntshav lim ntshav; hauv kev lag luam khoom noj khoom haus thiab dej haus, ntxiv cov tshuaj sib txuas sib txuas sib txuas PVP rau npias thiab dej tshuaj yej tuaj yeem tshem tawm npias thiab dej haus Cov polyphenols thiab cov tannins ntau dhau nyob hauv nws, thiab lawv tsis nyob hauv lawv, ua lub luag haujlwm hauv kev ruaj ntseg xim, kom ntseeg tau tias qhov tsw ntawm npias thiab tshuaj yej haus tseem tsis hloov pauv mus ntev, thiab tshem tawm qhov tsis txaus ntseeg. Nws yog cov dej haus zoo tshaj plaws thiab ruaj khov Nws tau siv dav hauv kev lag luam tshuaj niaj hnub, tshwj xeeb tshaj yog hauv cov tshuaj pleev ib ce, xws li PVP siv tshuaj tsuag plaub hau, uas muaj cov plaub hau zoo nyob ruaj khov, ci thiab ua kom lub zog ua haujlwm, thiab tsis nqus plua plav;
Hauv kev lag luam txheej txheej, siv PVP' zaj duab xis tsim cov khoom zoo thiab siv PVP los ua tus neeg sawv cev txheej los tsim cov xim, zaj duab xis yog pob tshab thiab tsis cuam tshuam rau xim ntuj, thiab qis-molecular-hnyav PVP tuaj yeem ua tus number case. Tus number case muaj kev sib faib zoo ruaj khov thiab ua rau nws nyuaj rau Fading kev ua tau zoo; hauv polymer polymerization, PVP tuaj yeem siv los ua kom tuab rau polymer emulsion polymerization, tshem tawm polymerization thiab lwm yam txheej txheem tshuaj tiv thaiv los txhim kho kev ua tau zoo ntawm cov tshuaj.
Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, daim ntawv thov PVP tau dhau los ua ntau thiab dav dua, thiab tau siv rau hauv cov thev naus laus zis siab xws li cov duab kho duab, kho qhov muag fiber, kho qhov muag laser, thiab rub cov khoom txo. Lwm yam, xws li cov khoom siv hauv tsev, kev siv hlau, kev tsim hlau, kev siv hluav taws xob hauv kev tshawb fawb hauv lwm thaj chaw kuj tau ua tiav.
PVP thiab nws cov monomer NVP tau tsim los ntawm BASF J. Walter. Reppe siv acetylene ua cov khoom siv tseem ceeb. Txoj kev no hu ua Reppe method, tseem hu ua acetylene method. Xyoo 1950, American ISP lub tuam txhab, tom qab ntawd GAF lub tuam txhab Nws tau tsim tiav NVP cov kab tsim khoom raws li txheej txheem acetylene nrog BASF hauv Tebchaws Yelemees, thiab tom qab ntawd tsim ntau qib ntawm PVP cov khoom. Txog tam sim no, ob lub tuam txhab no tseem yog cov tuam txhab tsim khoom loj ntawm PVP cov khoom.
Txoj hauv kev siv acetylene siv acetylene, formaldehyde, hydrogen, thiab lwm yam raws li cov ntaub ntawv pib, hla dhau catalytic aldehyde ntxiv. Catalytic hydrogenation, catalytic dehydrogenation los tsim lub nplhaib, amination, thiab alkyne ntxiv rau los ua ke monomer NVP, thiab tom qab ntawd polymerize nws nyob hauv qee qhov xwm txheej PVP nrog qhov hnyav sib txawv tuaj yeem tau txais. Copolymerization ntawm NVP nrog rau lwm cov monomers, xws li vinyl acetate, acrylamide, thiab lwm yam, kom tau txais copolymerized PVP, lossis ntxiv tus tshwj xeeb crosslinking tus neeg sawv cev nrog cov pab pawg bifunctional, xws li N, N-methylenebisacrylamide, thiab lwm yam. tawm kom tau txais cross-linked PVP. Vim tias cov khoom siv tseem ceeb acetylene siv hauv txheej txheem acetylene yuav tsum tau ua haujlwm nruj, cov txheej txheem yuav tsum tau ua nyob rau hauv kev kub siab thiab qhov kub thiab txias, uas xav tau cov cuab yeej siv siab, txheej txheem ntev ntws thiab cov cuab yeej loj, tsuas yog tsim rau kev tsim khoom loj thiab tsis tsim nyog rau kev tsim cov tuam txhab tsim khoom me thiab nruab nrab, kom txog tam sim no tsuas yog BASF hauv Tebchaws Yelemees thiab ISP cov tuam txhab hauv Tebchaws Meskas siv cov txheej txheem no los tsim cov khoom NVP thiab PVP.
