Abstract:
In this study, phosphate-based polycarboxylate superplasticizer (PPS) was successfully prepared via precise design and control over the molecular structure. Macromolecules with pendant chlorine groups are synthesized via free radical polymerization (FRP) and atom transfer radical polymerization (ATRP) of 2-hydroxyethyl acrylate, vinylbenzyl chloride and isoamyl alcohol polyoxyethylene ether in the presence of initiator, chain transfer agent and metal complex. The subsequent Arbuzov reaction (AR) between trimethoxyphosphine and chlorine groups of macromolecules gave rise to new type of PPS. The molecular structure of PPS is determined by Fourier Transform Infrared Spectroscopy, 1H Nuclear Magnetic Resonance and Gel Permeation Chromatography, respectively. The surface tension, Zeta potential, adsorption behavior and application performance in concrete are measured. The result shows that PPS we prepared has excellent clay-inerting and high slump retention capability.
