Abstract

In this study, Polycarboxylate (PC) superplasticizers based on acrylic acid (AA) were synthesized via free-radical copolymerization with an ethylene glycol monomer and characterized. The temperature of polymerization (ranging from 50 °C to 70 °C) appeared to be the key operating factor governing the chemical structure of the superplasticizers. The chemical structures of the products were analyzed by gel permeation chromatography, Fourier transform infrared spectroscopy and nuclear magnetic resonance. The results showed that the PCs synthesized at different polymerization temperature have similar functional groups but the temperature has affected on the molecular weight (MWs) and MW distribution. By increasing of temperature of polymerization the MW of PC has increased.
