Copolymers ntawm nvp thiab esters
Esters yog cov chav kawm tshaj plaws ntawm cov tebchaw rau PVP kev hloov kho. Feem ntau hais lus, Ester sib txuas cov copolymerized nrog NVP xa mus rau estres uas muaj unsaturated ob-} Daim ntawv cog pawg vinyl. Tom qab cov NVP copolymerization ntawm NVP thiab esters, ntawm ib sab tes, yog li kev txhim kho cov kev ua kom zoo dua, yog li txhim kho qhov yooj ntawm cov ntawv qhia copolymer. Ntawm qhov tod tes, muaj cov pab pawg hydrophobic hauv cov khoom lag luam uas ua kom muaj peev xwm tswj hwm nws cov duab uas muaj cov av noo. Feem ntau, esters suav nrog dimethylene sau, propylene acetate, methacrylate, propylene diacetate, metharacrylate, thiab lwm yam.
N - vinyl pyrrolidone (nVP) / Vinyl acetate (Vap Acetate (Vap) Nws yog qhov muaj xim tsis muaj xim thiab pob tshab, soluble me ntsis hauv cov kuab tshuaj organic, etyl acetate, thiab lwm yam kom yooj yim hlawv. Vap resin khaws cov haujlwm ntawm PvP ua cov polymer, thaum kov yeej qhov tsis zoo ntawm PVP tus nqi siab. Tsis tas li ntawd, Vap Resin muaj zaj duab xis zoo - ua cov khoom. Txij li nws qhia hydrophobic vinyl acetate units rau nws cov qauv molecular, yog li nws yuav tsis dhau los ua cov av noo nyob ib puag ncig thiab ntev muaj peev xwm tswj tau tus hairstyle. Xyoo 1985, vim yog kev txiav npluav ntawm Freon, propane / Butane tau dhau los ua lub tebchaws PvP / VA / VA / VINYCER Propionate Copolymer. Qhov nce ntawm kev faib ua feem ntawm Vinyl Propionate ua cov copolymer ua cov decrocarbon soluber mus txog 40%. Nyob rau hauv dav dav, vp: va: VA: VA: VAM:= 30}}}}}}}}
Copolymers ntawm nvp thiab acids
Metharacrylic Acid tam sim no yog cov siv kua qaub feem ntau rau cov npe ntawm NVP. Metharacrylic acid yuav tsum tau neutralized thaum siv, thiab cov lej nruab nrab yog qhov nyiam 80 {} 100%. Txij li nvp yog yooj yim hydrolyzed nyob rau hauv acidic tej yam kev mob, thiab acidity thiab alkalinity muaj kev ruaj ntseg ntawm pvp, tus nqi pH yuav tsum tau nruj me ntsis tswj thaum lub sijhawm copolymerization. Ib qho nyiaj ntawm koh tuaj yeem muab ntxiv ua ntej polymerization kom ntseeg tau tias alkaline tej yam kev mob rau polymerization. Cov polymer tau txais los ntawm cov tshuaj copolymerization ntawm NVP thiab acidic tshuaj yog anionic, muaj qhov zoo ntxuav, muaj qhov muaj peev xwm zoo, thiab tsis yooj yim los nqus ya kom noo noo. Piv txwv li, cov yeeb yaj kiab nrov tshaj plaws {{} Nyeem cov tshuaj polymer pvp / metylancrylate / metyl acrylate / metyl acrylate
(1) Qhov sib xyaw nrog cov roj / Butane yog siab npaum li 70% lossis ntau dua;
(2) Elasticity ntawm zaj duab xis yog qhov zoo heev, thiab tsis muaj lub tais yas xav tau ntxiv;
(3) Cov qib ntawm nruab nrab tsis cuam tshuam rau cov plaub hau -} ™ kho ua haujlwm thiab yog ib qho yooj yim ntxuav tawm;
(4) Grey zoo thiab tsis yooj yim rau tev tawm;
(5) CARL muaj zog khaws cia. Hauv huab cua huab cua huab cua, cov plaub hau muaj elasticity zoo thiab cov duab khaws cia thiab yuav tsis nplaum.
Copolymers tsim los ntawm nvp thiab cov ntsev ua haujlwm ammonium
Cov tshuaj ntsuab amine hauv cov molecules (xws li qualymerized nrog nVP los ua cov khoom siv polyqumination uas muaj cov cationic units hauv cov kab ke molecular. Nyob rau ntawm cov sam thiaj li qub, cov saum npoo ntawm cov plaub hau fibers muaj anionic tus yam ntxwv. Kev siv cations yuav pab tso nyiaj thiab Adsorb, txhim kho qhov ncaj thiab muaj kev sib txawv rau cov plaub hau, thiab muaj qee yam cuam tshuam. Polyquammalmarary ammonium compound muab ntev {}}} kav khi, kev ua haujlwm ntev thiab lub zog uas yog cov plaub hau plaub hau. Xws li Copolymers tau siv dav hauv cov duab cua daj cua dub, tshuaj zawv plaub hau thiab muaj cov tshuaj muaj ntau, ntxiv rau cov khoom lag luam mousse mousse. Lawv ua cov plaub hau ntub yooj yim los zuag tsis muaj Tangling, thiab thaum cov plaub hau dries, ci ntsa iab, thiab curly, ib yam li cov plaub hau ntub.
Kev siv PvP -} Raws li cov pej xeem zoo nkauj yog qhov tseem ceeb ntawm Mousse plaub hau ua npuass thaum xyoo 1980s. Raws li tsab ntawv qhia txog cov tshuaj pleev ib ce, cov koom haum Sweepance (CTFA), polyquare-16, polyquare-16, polyquare-5, polyquacymers-16, polyquare-16, polyquare-5, polyquacymers-4, polyquare-5, polyquacymers-16, polyquare-5, polyquare Ammoly salts. Piv txwv li, Polinququare-16 sawv cev rau plaub polymers: PVP / DMP / DMAF / DMAF / DMAF / DMAF / DMAFER Sulfate ntsev, thiab lwm yam ua ke tau zoo heev.
Copolymers tsim los ntawm nvp thiab amides
NVP nws tus kheej yog rau cov chav lactam ntawm cov tshuaj, thiab nws cov khoom zoo ib yam li cov neeg nyob, thiab nws muaj kev sib raug zoo. Xaiv cov neeg nyob nrog ntau methyl pawg ua cov pab pawg uas tsis yeem txo cov dej nqus dej nqus ntawm PVP thaum tswj nws cov kev ua haujlwm qub. Kho cov piv ntawm NVP rau cov lus qhia hauv cov copolymer, lossis xaiv cov solubility, tuaj yeem hloov pauv ntawm solubility, viscosity thiab lwm yam kev ua tau zoo ntawm copolymer cob. Cov solubility, viscosity thiab lwm yam kev ua tau zoo ntawm cov ntawv sau ua ke ntawm NVP caprolyslate coprolyslate coprolyslate coprolacylate Propellants. Nws siv kuj tuaj yeem txo cov hygroscopicity ntawm cov polymer. Lwm tus monomer, dimethylaminoethyl methacrylate, tuaj yeem nce curl retentent muaj peev xwm ntawm cov plaub hau, uas tuaj yeem txo cov polymer siv. Cov Cheebtsam vp thiab dimethylaminoethyl metacrylate hauv cov copolymer yog cov yeeb yaj kiab zoo nkauj, yog li cov plaub hau kev siv tau tuaj yeem raug txo kom zoo, thaum nws cov plaub hau curl khaws cia yog Tseem zoo heev. Qhov sib raug zoo ntawm cov copolymer nrog prosylene / Butane yog siab npaum li 70%. Thaum cov plaub hau tau kho nrog cov khoom tsim nrog nws, nws yuav qhia "ntub" thiab ci ci me ntsis ib zaug nws qhuav tag. Lub solubility ntau ntawm terpolymer dav heev thiab tuaj yeem siv rau hauv txhua hom plaub hau styling tus neeg sawv cev. Nws ua ke sib xyaw ua ke thiab txias rau hauv ib qho, thiab yog hom tshiab ntawm zaj duab xis- sib sau polymer nrog kev tsim kev txhim kho zoo kawg nkaus.
Lub ntsiab
Txij li thaum PvP hloov lub plhaub pob zeb ua cov txheej txheem styling, txoj kev loj hlob thiab tam sim no xwm txheej ntawm pvp stying cob cov khoom yog kwv yees li nram no:
(1) los ntawm ib tus pvp homopolymer mus rau lub siab- Kev ua yeeb yam pvp hloov copolymer tsim los ntawm copolymerization ntawm ntau tus monomers
(2) Los ntawm ib qho kev ua haujlwm styling ua rau ib qho styling polymer nrog ntau-}}}}}}}} kev mob thiab UV tsis kam.
(3) Vim Kev Tiv Thaiv Kev Tiv Thaiv Ib Puag Ncig, cov ntsiab lus ntawm cov khoom siv volatile (VOC) hauv SIZING RESIZING RESIZING CRASTERS yog txwv. Yog li ntawd, thaum tsim qauv thiab synthesizing pvp series sizing resins, hydrocarbon solubility thiab sib xyaw ua ke tau dhau los ua kev xav tsis tau thiab cov kev tshawb fawb.
