Polycarboxylate Superplasticizer PCEe aofia ai macromolecular tuufaatasi ma vaega sulfonic acid, vaega carboxyl, vaega amino, ma filifili itu polyoxyethylene, ma isi, i le vai vaifofo, e ala i le mataupu faavae o free radical copolymerization synthesis o polymers ma se fausaga selu Surfactant.

O mea mata'ina autu e mana'omia mo le tu'ufa'atasiga oFausia vaila'au Vai fa'aitiitia Polycarboxylate Superplasticiero: methacrylic acid, acrylic acid, ethyl acrylate, hydroxyethyl acrylate, sodium allyl sulfonate, methyl methacrylate, 2-acrylamido- 2-Methacrylic acid, methoxy polyoxyethylene methacrylate, ethoxy polyethylene glycol acrylate, e mafai ona faʻaaogaina allyl ether, ma isi. i le faiga polymerization o: persulfate-faavae initiators , Benzoyl peroxide, azobisisobutyl cyanide; sui fa'aliliuina filifili: 3-mercaptopropionic acid, mercaptoacetic acid, ma isi.

O le polycarboxylic acid vai e fa'aitiitia ai vai auala fa'afefiloi o le: i totonu o se fagu lapotopoto pito i lalo ua fa'apipi'iina i se fa'aoso eletise, se thermometer, se masini pa'u, ma se reflux condenser, o le polymerization monomer solution ma le vaifofo amata o lo'o fa'aopoopo malie i lalo e ala i le fa'avevela i totonu o le vai ta'ele. Pe a filifilia le polymerization monomer , O le iunivesite ma lona fua faʻatatau tauvaga e tatau ona mafaufau atoatoa. O le vevela o le tali e mafai ona fuafuaina e tusa ai ma le ituaiga monomer tali patino. E masani lava, o le vevela i le vevela o le 70 ~ 95 ℃ e mafai ona filifilia e pei o le vevela tali.

Tu'u le vaifofo monomer i totonu o le itula e tasi, ona faapa'u lea i totonu o le 20 minute faaopoopo le vaifofo amata o totoe, ma iu ai ina faateleina le vevela i le 5°C, faaauau le tali mo le 1h, ma a uma ona tuutuu i lalo le vevela i le 40°C, faalēaogāina ma lafoa'i.
