Abstract

In this work, we synthesized a new viscosity modifying agents with AA, AM as monomer and ammonium persulfate as initiator. Through the discussion on the AA dosage, the polymerization conditions, we determined the optimum technological conditions of the new VMA: the optimum molar ratio of AA to AM is 1:1, the dosage of initiator is 2wt% of all the monomers. The optimum polymerization time is 3h at 65 .The new VMA can significantly improve yield stress and apparent viscosity of cement paste.
