| Abstract: | The author prepared sodium polyacrylate with different relative molecular mass via aqueous solution polymerization in the presence of Na2S2O8 as initiator and NaHSO3 as chain transfer agent by regulating the molar ratio of the initiator to the chain transfer agent.The effect of the relative molecular mass of sodium polyacrylate as dispersing agent on dispersancy of calcium carbonate was studied.The results show that the dispersancy effectiveness of the sodium polyacrylate is closely dependent on its relativ... |
