| Abstract: | The methoxyl poly(ethylene oxide)(MPEO-A-1000)-modified polyamidoamine dendrimers(MnG,n = 4.0,5.0) were prepared via Michael addition reaction.The effects of the filler retention and strength in the hardwood were investigated when added MnG and their dual additive with poly(sodium acrylate) or sodium acrylate-modified PAMAM.The results show that the M4.0G and its dual additive with sodium acrylate-modified PAMAM can improve paper filler retention and strength effectively. |
