| Abstract: | In this paper,low molecular weight polyacrylic acid was prepared by solution polymerization in the presence of ammonium persulfate as initiator.The effects of polymerization conditions on the molecular weight of polyacrylic acid were investigated in detail.The results showed that the optimum conditions for proper molecular weight about 3 000 applicable to solution chain for hyperdispersant were as follows:the concentration of initiator was 4.5%,the monomer concentration was 25%,the polymerization temperatur... |
