Synthesis and Performance of Polycarboxylic Acid
Abstract A new type of polycarboxylic acid superplasticizer (G18-PCEs) containing crosslinked linkage was synthesized by the method of the first esterification and then polymerization. Its monomer and polymer structure were confirmed by 1H nuclear magnetic resonance (NMR) spectroscopy and High-performance liquid chromatography.

by year, but liquid polycarboxylate superplasticizer cannot meet the needs of these industries. At present, there are researches on solid polycarboxylic superplasticizer in China. We use spray drying technology or bulk polymerization to obtain powder polycarboxylic superplasticizer usually[2].
Synthesis and properties of an amphoteric polycarboxylic acid
A novel amphoteric polycarboxylic (APC) acid-based superplasticizer was prepared by solution copolymerization from maleic anhydride, allyl polyethylene glycol, and methacryloxyethyltrimethyl ammonium chloride (DMC). The cationic monomer DMC was introduced for improving the performances of sulfoaluminate cement (SAC) with APC.
Preparation and properties of polycarboxylate
In this paper, ethyl glucose (Glc), 2-amino-4-methyl-5-phospho-3-pentenoate (AMEPA) and p-toluene sulfonic acid (PTS) were esterified, and the esterified products were polymerized with acrylic acid...
Concrete Water Reducer - Superplasticizers
7. Since the dosage of polycarboxylic acid superplasticizer is very small, the water reduction rate is high. The use of polycarboxylic acid superplasticizers to prepare various types of high-performance concretes above C45 can greatly reduce project costs and has significant technical and economic benefits; it is used to prepare concrete below C45, although the cost of polycarboxylic acid
- What is superplasticizer polycarboxylate?
- Superplasticizer Polycarboxylate Superplasticizer is a new generation superplasticizer based on modified polycarboxylate particularly recommended for ready mixed concrete and civil engineering construction. Its particular configuration allows its delayed adsorption onto the cement particles and disperses them efficiently.
