Research on the Synthesis and Performance of High-Performance Polycarboxylate Superplasticizers
In this study, high-workability polyc-arboxylate superplasticcizers (PCEs) were prepared throug- h aqueous radical polymerization using ethylene glycol monovinyl ether (EPEG-3000), acrylic acid (AA), and a polymeric functional monomer (a small unsaturated monomer with phosphate ester groups) as raw...

| description | In this study, high-workability polyc-arboxylate superplasticcizers (PCEs) were prepared throug- h aqueous radical polymerization using ethylene glycol monovinyl ether (EPEG-3000), acrylic acid (AA), and a polymeric functional monomer (a small unsaturated monomer with phosphate ester groups) as raw materials. Hydrogen peroxide/sodium bisulfite was employed as the initiation system, and mercaptoethanol (ME) served as the chain transfer agent. Based on single-factor experiments, the effects of the raw materials and theirquantities on the performance of the PCEs were investigated. Optimal performance was achieved under the conditions of an acid-to-ether ratio of 4.51, a reaction temperature of 20°C, and with the polymeric functional monomer and chain transfer agent dosages set at 2.22% and 0.44% of the EPEG-3000 mass, respectively. Structural characterization confirmed that the molecular structure of the synthesized product matched the expected design. |
