Glycidyl Methacrylate (GMA) o se monomer o loʻo i ai faʻatasi faʻalua acrylate ma vaega epoxy.Acrylate fa'alua fa'alua e maualuga le gaioiga, e mafai ona o'o i le tali-polymerization, ma e mafai fo'i ona fa'atasi ma le tele o isi monomers;epoxy vaega e mafai ona tali atu i le hydroxyl, amino, carboxyl poʻo le acid anhydride, faʻafeiloaʻi le tele o vaega galue, ma faʻateleina ai galuega i le oloa.O le mea lea, o le GMA o loʻo i ai le tele o faʻaoga i le faʻaogaina o meaola, polymer synthesis, polymer modification, mea tuʻufaʻatasia, mea faʻamalolo ultraviolet, faʻapipiʻi, faʻapipiʻi, paʻu, vailaʻau fibre pepa, lolomi ma vali, ma le tele o isi fanua.

Faʻaaogaina o le GMA i le paʻu paʻu

O le pa'u pa'u akrilic o se vaega tele o pa'u pa'u, e mafai ona vaevaeina i resini fa'a-hydroxyl, resini fa'a-carboxyl, resini fa'a-glycidyl, ma resini amido e tusa ai ma vaila'au fa'amalolo eseese na fa'aaogaina.Faatasi ai ma i latou, glycidyl acrylic resin o le sili ona faʻaaogaina paʻu paʻu resini.E mafai ona faia i ata tifaga ma vailaau faʻamalolo e pei ole polyhydric hydroxy acids, polyamines, polyols, polyhydroxy resins, ma hydroxy polyester resins.

Methyl methacrylate, glycidyl methacrylate, butyl acrylate, styrene e masani ona faʻaaogaina mo polymerization radical free e faʻapipiʻi le GMA type acrylic resin, ma dodecyl dibasic acid o loʻo faʻaaogaina e fai ma sui faʻamalolo.O le pa'u pa'u acrylic ua saunia e lelei le faatinoga.O le fa'agasologa o le fa'aogaina e mafai ona fa'aogaina le benzoyl peroxide (BPO) ma le azobisisobutyronitrile (AIBN) po'o a latou fa'afefiloi e fai ma amataga.O le aofaʻi o le GMA o loʻo i ai se faatosinaga tele i le faʻatinoga o le ata faʻapipiʻi.Afai e laʻititi tele le aofaʻi, o le maualuga o le faʻaogaina o le resin e maualalo, o le faʻamaloloina o faʻamaufaʻailoga e laʻititi, o le maualuga o le fesoʻotaʻiga o le ata faʻapipiʻi e le lava, ma e le lelei le aʻafiaga o le faʻapipiʻiina o ata.

Faʻaaogaina o le GMA i le suiga o le polymer

E mafai ona fa'apipi'i le GMA i luga o le polymer ona o le i ai o se fusi fa'alua acrylate ma gaioiga maualuga, ma o le vaega epoxy o lo'o i totonu o le GMA e mafai ona tali atu i le tele o isi vaega fa'atino e fausia ai se polymer fa'atino.E mafai ona fa'apipi'i le GMA i polyolefin fa'aleleia e ala i metotia e pei o le fa'apipi'iina o vaifofo, fa'afefeteina fa'afefete, fa'apipi'iina o vaega mautu, fa'apipi'i fa'avevela, ma isi, ma e mafai fo'i ona fausia ai copolymers ma ethylene, acrylate, ma isi. e fa'amalo ai palasitika fa'ainisinia po'o ni mea fa'apipi'i e fa'aleleia atili ai le fetaui o faiga fa'afefiloi.

O le amataga e masani ona faʻaaogaina mo le suʻeina o le polyolefin e GMA o le dicumyl peroxide (DCP).O nisi tagata latou te faʻaaogaina le benzoyl peroxide (BPO), acrylamide (AM), 2,5-di-tert-butyl peroxide.Fa'ata'ita'iga pei ole oxy-2,5-dimethyl-3-hexyne (LPO) po'o le 1,3-di-tert-butyl cumene peroxide.Faatasi ai ma i latou, o le AM ​​e iai sona aafiaga taua i le faʻaitiitia o le faʻaleagaina o le polypropylene pe a faʻaaogaina e avea o se amataga.O le faʻapipiʻiina o le GMA i luga o le polyolefin o le a taʻitaʻia ai le suiga o le fausaga o le polyolefin, lea o le a mafua ai le suiga o le polyolefin's surface properties, rheological properties, thermal properties ma masini.GMA graft-modified polyolefin e faʻateleina ai le polarity o le filifili mole ma i le taimi lava e tasi e faʻateleina ai le polarity luga.O le mea lea, e fa'aitiitia le fa'afeso'ota'i i luga a'o fa'atupula'ia le fua o le fa'apipi'i.Ona o suiga i le polymer structure pe a maeʻa le suiga o le GMA, o le a aʻafia ai foi lona tioata ma mea faʻainisinia.

Faʻaaogaina o le GMA i le faʻaogaina o le resini faʻamalolo UV

E mafai ona faʻaaogaina le GMA i le faʻapipiʻiina o resini faʻamalolo UV e ala i auala eseese.O le tasi auala o le muamua maua se prepolymer o loʻo i ai vaega carboxyl poʻo amino i luga o le filifili itu e ala i polymerization radical poʻo le condensation polymerization, ona faʻaoga ai lea o le GMA e tali atu ai ma nei vaega faʻatino e faʻafeiloaʻi ai vaega photosensitive e maua ai se resin photocurable.I le kopi muamua, e mafai ona faʻaogaina comonomers eseese e maua ai polymers ma mea faʻaiʻu eseese.Feng Zongcai et al.faaaoga 1,2,4-trimellitic anhydride ma ethylene glycol e tali atu e synthesize polymers hyperbranched, ona faailoa atu lea o vaega photosensitive e ala i GMA e iu lava ina maua se resin photocurable ma sili atu alkali solubility.Lu Tingfeng ma isi na faʻaaogaina le poly-1,4-butanediol adipate, toluene diisocyanate, dimethylolpropionic acid ma le hydroxyethyl acrylate e faʻapipiʻi muamua se prepolymer ma faʻaoga faʻalua faʻamalosi, ona faʻafeiloaʻi lea e ala i le GMA E sili atu le malamalama-curable faʻalua faʻamaufaʻailoga e faʻaleagaina e triethylamine e maua le vai emulsion polyurethane acrylate.
