The compound polycarboxylic high performance superplasticizer was synthetize with sodium thiosul-fate(Na2 S2 O3 )and composite initiator,which using multimonomer of allyl polyoxyethylene ether (APEG), methyl allyl polyethenoxy ether (TPEG),acrylic acid(AA)and sodium allysulfonate (SAS)as raw materials. The excitation of monomer reactivity,polymerization reaction rate of system and decomposition rate of initiator was studied from the view of thermal dynamic.The correlation between monomer structure and property of the superplasticizer in different reaction temperatures was studied with the analysis of infrared spectroscopy.
