Abstract：The polycarboxylic series of water reducer was synthesized by using polyether monomer(TPEG),acrylic acid (AA)and 2-acrylamido-2-methyl propane sulfonic acid(AMPS) as the main materials.Researching the factors of monomer mole ratio,the polyether macromonomer side chain molecular weight by orthogonal experiment,and analyzing the influence of these factors on polycarboxylic water reducer.The results show that when initiator weight is 3000,n(AA)∶n(AMPS)∶n (TPEG)=3.25∶1.5∶2.0,the dispersing performance of compound water reducer is preferable.Under the above condition,the results show that dispersity performance of polycarboxylic water reducer is the best when the reaction temperature is 75 ℃C,and phenomenon about stratification or segregation is not found.
