Zhao Xian-zeng

Open publisher page 0 citations

Abstract

The polyacrylamide (PAM) with lower molecular weight was prepared by aqueous solution polymerization.The influence of reaction -temperature,amount of initiator and chain-transfer agent on molecular weight of PAM has been studied.EDTA can eliminate the effect of metal ion on molecular weight fluctuate.The polyacrylamide with molecular weight of(1.84.3)10~4 was prepared at 8090 when the concentration of initiator is 21510~3 mol/L and chain-transfer agent is 12.5 mol/L.
