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 atili vaega galue, ma aumaia ai le tele o 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.

Fa'aogaina o le GMA i le pa'u pa'u

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 ai le resini acrylic ituaiga GMA, ma o le dodecyl dibasic acid e 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 faʻapipiʻi GMA i polyolefin faʻaleleia e ala i metotia e pei o le faʻapipiʻiina o vaifofo, faʻafefeteina faʻafefete, faʻapipiʻi vaega malosi, faʻapipiʻiina o le radiation, ma isi, ma e mafai foi 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 faʻapupulaina 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 fa'atatau. Ona o suiga i le fausaga o le polymer pe a maeʻa le suiga o le GMA, o le a aʻafia ai foi ana mea tioata ma masini.

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 faʻaaoga lea o le GMA e tali atu ai ma nei vaega galue e faʻafeiloaʻi 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. O Lu Tingfeng ma isi na faʻaaogaina le poly-1,4-butanediol adipate, toluene diisocyanate, dimethylolpropionic acid ma le hydroxyethyl acrylate e faʻapipiʻi muamua ai se prepolymer ma fusi faʻalua faʻamalosi faʻamalosi, ona faʻafeiloaʻi lea e ala i le GMA E sili atu le malamalama-curable faʻalua faʻamaufaʻailoga e faʻafefe e le triethylamine e maua le vai emulsion polyurethane acrylate.
