摘要
Abstract
Polyacrylamides(PAM)were prepared by the free radical polymerization of acrylamide(AM) with nano-Fe2O3 as the photoinitiator.The efficiency of nano-Fe2O3 was compared with an organic initiator,thioxanthone-terminated poly(ethylene imine)(PEI-TX).The effects of nanoFe2O3 photoinitiation system under reaction conditions were investigated.The results indicated that,under the same conditions,the initiation efficiency of nano-Fe2O3 was lower than that of PEI-TX.The optimum reaction conditions for the photo-initiated polymerization system with nano-Fe2O3 as the initiator were 1.0 mmo/L nano-Fe2O3,20％(w) AM,light intensity of 9.9 mW/cm2 and reaction time of 20 min.PAM prepared with nano-Fe2O3 as initiator has better fiocculation performance than PAM prepared with PEI-TX as initiator.关键词
