- Abstract
Under the condition of unchangeable reaction time, the dosage of initiator and chain transfer agent, the molar volume of unsaturated double bond, we synthesized a series of polycarboxylate superplasticizer via free radical polymerization. These polycarboxylate superplasticizer had a similar structure except carboxyl density. They were investigated by Gel Permeation Chromatography (GPC) and High Performance Liquid Chromatography (HPLC). On this basis the properties of this PCE was evaluated through methods of rheological test. It showed that the dispersility was better as we increased the carboxyl density, while the risk of bleeding was increased.
