I-Polycarbox ye-Superplastikizer pceIqulathe i-macromolecular enamaqela e-Sulfonic Acid, amaqela e-carboxyl, amaqela e-Amino, kunye ne-polyoxyylene yecala le-Polyntment ye-Polyntmes ene-collymes ene-collymers enoluhlu lwe-profackent.

Ezona zinto zibalulekileyo ziyinto efunekayo kwi-synthesis yeUkwakhiwa kwamachibi amanzi ekhemikhali ye-Polycarboxylatezezi: methacrylic acid, acryccid acid, ethyl acrylate, i-ethocyl methacrylate, i-ethocy polythylene glyllate, i-allyl tether, njl. Abangeneleli abanokusetyenziswa kwinkqubo ye-polymerizazazazazali yile: Abaqalisi abasekwe kwi-Persoyl, i-Benzoyl Peroxoide, i-Azobisoby Sendaride; IArhente yokuThunyelwa kweChain: I-3-Mercaptopion Acid, Mercaptocetic acid, njl.

I-Polycarboxyylicy -cy Acid inciphisa iarhente Indlela ye-Synthesis yile: Kwi-flask esezantsi esezantsi ephethe umthambo wombane, ithemometha, isixhobo esiphosakeleyo, kunye nesisombululo se-morelmer, isisombululo sePolymerization songezwa ngokuthe chu ngendlela yokufudumeza. Xa ukhetha i-Polymerizaration Monomer, iYunivesithi enezinga zawo zokhuphiswano kufuneka ithathelwe ingqalelo ngokupheleleyo. Amaqondo obushushu asabelayo anokumiselwa ngokohlobo oluthile lokuphendula. Ngokubanzi, iqondo lobushushu kuluhlu lobushushu lwe-70 ~ 95 ℃ inokukhethwa njengamaqondo obushushu asabela.

Phosa isisombululo se-monomer kwiyure enye, emva koko siyihlise ngaphakathi kwimizuzu engama-20 esongeza isisombululo esisele, kwaye ekugqibeleni sandise i-5 ° C, kwaye emva kwe-C, ukukhutshwa.
