O le Glycidyl Methacrylate (GMA) o se monomer e iai fusiua faalua acrylate ma vaega epoxy. O le fusiua faalua acrylate e maualuga lona tali atu, e mafai ona faia se tali atu i le self-polymerization, ma e mafai foi ona copolymerized ma le tele o isi monomers; e mafai e le vaega epoxy ona tali atu i le hydroxyl, amino, carboxyl poʻo le acid anhydride, ma faʻaopoopoina ai nisi vaega galue, ma faʻateleina ai le aoga o le oloa. O le mea lea, e matua lautele lava le faʻaaogaina o le GMA i le organic synthesis, polymer synthesis, polymer modification, composite materials, ultraviolet curing materials, coatings, adhesives, leather, chemical fiber papermaking, printing and dyeing, ma le tele o isi matata.

Fa'aaogāina o le GMA i le valiina o le pauta

O vali pa'u acrylic o se vaega tele o vali pa'u, e mafai ona vaevaeina i ni hydroxyl acrylic resins, carboxyl acrylic resins, glycidyl acrylic resins, ma amido acrylic resins e tusa ai ma vaila'au fa'amamago eseese e fa'aaogaina. O le glycidyl acrylic resin o le vaila'au vali pa'u e sili ona fa'aaogaina. E mafai ona faia i ni ata tifaga ma vaila'au fa'amamago e pei o polyhydric hydroxy acids, polyamines, polyols, polyhydroxy resins, ma hydroxy polyester resins.

E masani ona faʻaaogaina le methyl methacrylate, glycidyl methacrylate, butyl acrylate, ma le styrene mo le free radical polymerization e faʻaputu ai le GMA acrylic resin, ma e faʻaaogaina le dodecyl dibasic acid e fai ma vailaʻau faʻamālōlō. O le ufiufi paʻu acrylic ua saunia e iai le faʻatinoga lelei. E mafai ona faʻaaogaina le benzoyl peroxide (BPO) ma le azobisisobutyronitrile (AIBN) poʻo a latou faʻafefiloi e fai ma amataga i le faiga o le gaosiga. O le aofaʻi o le GMA e iai sona aʻafiaga tele i le faʻatinoga o le ata vali. Afai e laʻititi tele le aofaʻi, e maualalo le tikeri o le crosslinking o le resin, e itiiti ni vaega o le faʻamālōlōina, e le lava le crosslinking density o le ata vali, ma e le lelei le teteʻe atu i le aʻafiaga o le ata vali.

Fa'aaogāina 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 iai o se acrylate double bond e sili atu lona gaioiga, ma o le epoxy group o lo'o i totonu o le GMA e mafai ona tali atu ma le tele o isi functional groups e fausia ai se functionalized polymer. E mafai ona fa'apipi'i le GMA i le modified polyolefin e ala i auala e pei o le solution grafting, melt grafting, solid phase grafting, radiation grafting, ma isi, ma e mafai fo'i ona fausia ai functionalized copolymers ma le ethylene, acrylate, ma isi. O nei functionalized polymers e mafai ona fa'aaogaina o ni fa'amalosi e fa'amalosi ai palasitika fa'ainisinia po'o ni compatibilizers e fa'aleleia atili ai le fetaui o faiga fa'afefiloi.

O le initiator e masani ona faʻaaogaina mo le faʻaleleia atili o le polyolefin e le GMA o le dicumyl peroxide (DCP). O nisi tagata e faʻaaogaina foʻi le benzoyl peroxide (BPO), acrylamide (AM), 2,5-di-tert-butyl peroxide. O initiator e pei o le oxy-2,5-dimethyl-3-hexyne (LPO) poʻo le 1,3-di-tert-butyl cumene peroxide. O nisi o ia mea, o le AM ​​e iai sona aafiaga tele i le faʻaitiitia o le faʻaleagaina o le polypropylene pe a faʻaaogaina o se initiator. O le faʻapipiʻiina o le GMA i luga o le polyolefin o le a iʻu ai i le suiga o le fausaga o le polyolefin, lea o le a mafua ai ona suia meatotino o le polyolefin, meatotino rheological, meatotino vevela ma meatotino faʻainisinia. O le GMA graft-modified polyolefin e faʻateleina ai le polarity o le filifili molecular ma i le taimi lava e tasi e faʻateleina ai le polarity o le fogaeleele. O le mea lea, e faʻaitiitia ai le tulimanu o le fesoʻotaʻiga o le fogaeleele aʻo faʻateleina le fua faatatau o le faʻapipiʻiina. Ona o suiga i le fausaga o le polymer pe a uma le faʻaleleia atili o le GMA, o le a aʻafia ai foʻi ona meatotino crystalline ma faʻainisinia.

Fa'aaogāina o le GMA i le fa'aputuga o le resin e mafai ona fa'amalolo i le UV

E mafai ona fa'aaogaina le GMA i le fa'aputuga o resins e mafai ona fa'amalolo i le UV e ala i le tele o auala fa'aputuga. O le tasi metotia o le mauaina muamua lea o se prepolymer o lo'o i ai le carboxyl po'o amino groups i le side chain e ala i le radical polymerization po'o le condensation polymerization, ona fa'aaoga lea o le GMA e tali atu ai ma nei functional groups e fa'aofi ai vaega photosensitive e maua ai se resin photocurable. I le copolymerization muamua, e mafai ona fa'aaogaina comonomers eseese e maua ai polymers ma meatotino mulimuli eseese. Na fa'aaoga e Feng Zongcai ma isi le 1,2,4-trimellitic anhydride ma le ethylene glycol e tali atu ai e fa'aputu polymers hyperbranched, ona fa'aofi lea o vaega photosensitive e ala i le GMA e iu ai ina maua se resin photocurable ma sili atu le solubility alkali. Na faʻaaogā e Lu Tingfeng ma isi le poly-1,4-butanediol adipate, toluene diisocyanate, dimethylolpropionic acid ma le hydroxyethyl acrylate e muamua faʻaputu ai se prepolymer faʻatasi ai ma fusi faʻalua e maaleale i le malamalama, ona faʻaofi lea e ala i le GMA. O fusi faʻalua e mafai ona faʻamalolo e le malamalama e faʻaleaogaina e le triethylamine e maua ai le polyurethane acrylate emulsion e feaveaʻi i le vai.
