Abstract: The effects of composition of reaction system and the quantity of solvent on the yield of the crosslinking copolymer of Br terminated poly (ethylene oxide) (BrPEOBr) with poly (ethyleneimine)(PEI) were investigated.When 8.0 g BrPEOBr was reacted with 1.0 g PEIin 100 mL DMSO at 120℃ for 5 h, all the PEIcould be converted into crosslinking copolymer, and the conversion of BrPEOBr reached 94.3%.The copolymer (PEO-PEI) can absorb the deion-ized water 80 times its own weight.Further converting the copolymer into quaternary ammonium chloride, it can absorb the deionized water 250 times its own weight.
Key words: Poly (ethylene oxide), Poly (ethyleneimine), Crosslinking copolymer, Quaternary ammonium chloride, Water absorption capacity
