high performance polycarboxylic type water-reducing agent WD-1 is synthesized in following steps: 1.Methyl acrylic acid is esterized with polyethylene glycol;2.The ester intermediate is polymerized with sodium allylsulfonate and methyl acrylic acid.The polymerization degree of PEG(n)
the temperature of esterification(T)and their effect on major performance of water reducing agent WD-1 are discussed.The product is characterized by IR;and the total performance is tested.The results show that the water-reducing ratio of WD-1 is 26.9% when n=9 and T=80?℃.
