| Abstract: | Low molecular weight （105 to 106）polyacrylamide can be made through aqueous solu-tion polymerization with acrylamide as monomer,ammonium persulfate as an initiator,and sodi-um formate as the chain transfer agent.This paper discusses the effect of monomer concentra-tion,initiator concentration,the amount of chain transfer agent,reaction temperature and reac-tion time on molecular weight. |

| Keywords: | low molecular weight polyacrylamide aqueous solution polymerization amount of chain transfer agent |
