Direct Polycarboxylate superplasticizer monomer

Sun and Huang used direct polymerization to make new PCE, which was directly polymerized using allyl polyethylene glycols, methyl acrylate, maleic anhydride, and ammonium persulfate. The influence of monomer ratio, initiator dosage, reaction time, reaction temperature, and dropping time on the dispersing ability and fluidity-retaining ability of PCE was studied. Based on the orthogonal experiment, the best process was obtained. The comparison was made on the performance of the product synthesized and another widely used product at present, which was synthesized by methoxy polyethylene glycol (MPEG) and methyl acrylic acid (MAA). Lv et al. Synthesized a new kind of PCE by introducing citric acid to the polycarboxylic molecule as a branch to solve concrete’s slump loss, bleeding, and segregation. Excellent PCE was obtained when n(PEGAA): n(PEGCM): n(MA): n(AA): n(SAS) = 1: 0.1 : 0.3: 0.2: 0.05, the initiator was 0.8% (NH4)2SO4 by mass of vinyl monomers, the reaction time was 2-3 h, and the reaction temperature was 80°C. It was shown in the application result that the water-reducing ratio of the product reached 32%, retardation time extended by five h, and concrete with PCE had excellent slump retention, without segregations, and with high compressive strength. A two-step process completed direct polymerization to obtain PCE, which could get unique products with high purity. However, it was also considered to cost more due to its complexity.

Ferrari et al. Synthesized a series of PCEs depending on the branch length, density, and molecular weight and did some tests. The results showed that fractions of higher molar weight were adsorbed to a more significant extent than fractions of lower molecular weight. Yang used azobisisobutylamidine hydrochloride (AIBA·2HCl) as an initiator in polymerization of polyoxyethylene allyl ether (APEG) and maleic anhydride (MA) to synthesize PCE-1. Also, Isoamyl enol polyoxyethylene ether (TPEG), the activity of acrylic acid (AA), and methacrylic sulfonate (MAS) were used to synthesize PCE-2. The results showed that when mixing PCE with concrete, the slump-retaining ability and the performance of late compressive strength of concrete enhancement were better than the similar PCE initiated by ammonium persulfate (APS). Yuused allyl alcohol polyoxyethylene (APEG), acrylic acid (AA), maleic anhydride (MAD), and sodium methyl acrylamide (SMAS) as primary raw materials to gain PCE. The compatibility between PCE and cement was excellent. The configuration concrete had excellent characteristics, such as lower slump loss. The water-reducing ratio in concrete was 32.4% at the solid dosage of 0.3%. Du used maleic anhydride, methyl methacrylate sulfonic acid sodium, allyl base polyethylene glycol (PEG) as raw materials, and ammonium persulfate as initiator. He synthesized poly Malay PCE, according to the cement paste slurry flow degree tests to determine the best synthetic process conditions for the poly Malay PCE: maleic anhydride, PEG, and methyl methacrylate sulfonic acid sodium with the best molar ratio 4 : 1: 0.2. PEG with a molecular weight of 2400 was selected, the initiator was added in two portions, and the polymerization was carried out at 80°C for 5 hours. Hu researched the influences of a single factor in synthesis, confirming the optimal ratio of raw materials, testing the performance of PCE, and characterizing the molecular structure. It was indicated in test results that the expected functional group was introduced into the system. According to the measured data of GPC, the Mw, Wn, MCL, and SCL of APEG and TPEG type PCE were followed by 14700 g/mol, 103000 g/mol, 7540 g/mol, and 84500 g/mol, 2.5 nm and 1.8 nm, and 15.3 nm and 15.3 nm.
