| Abstract: | The dibenzo-14-crown-4 was synthesized by the ultrasonic synthetic method,and after it was polymerized with formaldehyde,the linear polymer was obtained.The polymer was co-polymerized with the monomers of PU(polyurethane) foam,and network copolymer(IPN)was achieved.The experiment of separating lithium and magnesium was processed using the network copolymer.The experimental result shows that the effect of separating Li+ and Mg2+ is good and the crown PU foam will become a new kind of materials for separating... |
